authoring space overhaul
this update tries to improve the user experience of the authoring space.

added codemirror for xml editor and script tags in colorful editor
added possibility to deactivate codemirror in author settings
added dropdown menu to insert problem templates into xml editor (thanks to tobias reinhardt)
added feature of saving current scrollposition on save when editing problems
added possibility to fold blocks in colorful editor, this state will be saved and restored
added shortcuts to create empty problems, html files and directories

and other smaller features and bugfixes

- IE11 not displaying HTML5/javascript Geogebra version; fall back to
  Java applet for now.

- Update to GeoGebra 4.4.3.0

Do not translate twice

- Correctly detect browser version for IE, in cases where Chrome Frame
  plug-in is in use.
- More comprehensive checking for HTML5 support for Geogebra , based on
  decoding of user agent at log-in.
  - HTML5 used for:
    Chrome: version 14 or later
    Safari: version 536 or later (version 8536 for mobile safari).
    Firefox: version required dependent on os.
    IE: version 10 or later
- Error message displayed when Java is disabled is different if user's
  device is Ipad, Ipod or Iphone.

- Improve readability of rules log in modal window.

Use jPicker to choose colors on background function plot.

Installing the HTML5 version of GeoGebra.

HTML5 compatibility

HTML5/JavaScript does not understand underscores in applet IDs

Further work on HTML5.

TODO: Need to replace "_" in applet-ID, as JavaScript implementation ignores it.

Prepare for JavaScript/HTML5

Add some robustness: give warning if labels are used multiple times or before being defined.

Make it so the components of the sum vector can be shown

Vector sum tool

Nail down vectors after problem is no longer answerable

Unfortunately, "undev" does not evaluate to undev

Eliminate some copy/paste coding

Eliminating more popups

Be able to adjust width and height, so you can use 1:1 aspect ratio

Check for attachment of list of objects

Better output of vector coordinates in Rules Log

Custom function plot rule

Evaluate vector conditions with respect to each other

Sum vector rule working

Sum-Vector rule works with comma-separated list

Vectors attached to objects working

Angle checking

Length rule working
Use absolute error

Vector lengths and angles

Starting on vector rule evaluation

Sum of vectors attached to an object

Work on vector rules

More elegant way of doing the point coordinates and their updates

Calling the update routines

Angle display

Work in progress: vectors

Work in progress: objects and vectors

GeoGebra 4 - stable release

Formatting coordinates involving exponents for GeoGebra

In ruleslog, single quotes need to be escaped to JavaScript

Be able to access labels when defining values

Values in functionplotresponse rules can be evaluated

Allow for piece-wise defined functions if splines seamlessly connected

- Needs concatenator instead of ; (added in rev 1.47).

Trying to increase Mac compatibility

Indices greater than 9 need brackets.

Answer splines are green and don't show their arrows.

Continued work on answer spline

Work in progress on using splines as answers

New bytecode that works better with GeoGebra 4.0

Further work on multiple instance problem

New version of GeoGebra

Typo

Sanity check of rule boundaries

Junior Management School getting its own server

Do not allow the slider length to go to zero, so the point does not get "stuck."

Documentation for functionplotresponse

Bug #6401: Check for minimum and maximum length in corner case of borders being start and end

Lock down entered spline when problem cannot be answered anymore

Show answer functionality

Color for background plots

If the axes are off screen, the axis labels are put into the corners

Improvements to colorful editor

Fix bug in backgroundplot

New applet code and integral.

Code cleanup

New interface code

Beta version of GeoGebra

More examples
Correction for undefined upper value on boundaries

Functionplotresponse hints working

Correctly deal with "undef" as desired value

* Debug window
* Minimum and maximum length of ranges
* derivative -> derivativeorder
* Another template

Now finally: the hopefully correct second derivative

* Implement tolerance on rule-level
* Template

Better layout in colorful editor. Debugging code commented out.

Labels appear to be working. Still has debugging code.

Start and end labels work in plots

Colorful editor

(Hopefully) correct application of chain rule for second derivative

* Even simpler is even better
* Implemented checking properties over a range
* Left to do:
 - colorful editor for functionplotrule
 - labels for plots that are not bound to coordinates
 - fix second derivative
 - remove debug code

Simpler is better: more precision, less interpolation.
Implement gt, lt, etc
Deal with undef as desired value

<splinerule> becomes <functionplotrule>, as other elements may be added
Start implementing rules
Still contains debug code

Starting to implement the spline rule tag

Using existing index-mechanism instead of introducing new 'label'

Clean up debugging
First and second derivative calculation and interpolation

Better return codes

Saving my work: server-side function interpolation.
Seems to work but still has debug code in it.

Automatically detect if spline is a function, don't reduce tries if not a
function

Server-side calculation of the splines, based on parameters

Remember which splines go with which response

Need to wait till all applets on the page are loaded before starting to
initialize them.

Server-side spline calculation

Axis Labels

Colorful editor for the existing functionplotresponse tags.

Recognize previous tries
Work on colorful editor

Coordinates can be zero ...

Complete server round-trip: storing and restoring student answers

Handing back spline data in form fields for server evaluation

Correct scaling and maximum spline order

Now draws splines

<spine>-tag

Part of the server communication and comments

Axes parameters and background plots
