XHTML:
Added quotation marks to HTML attribute values

- Regular Expression for both http and https.

Moved POD comments to bottom of file

Added/created/modified POD documentation

Change arguments accepted by lonnet::appenv() to:
1. reference to hash
2. (optional) reference to array.

Change all instances where lonnet::appenv() is called to replace first argument passed (originally a hash) to a reference to the hash.

- Modify lonnet.pm rev 1.35 code intended to prevent "dangerous" modifications of the environment, so it will actually do this.
- Allow these modifications to be made in certain instances:
   DC switching to adhoc role
   CC switching to a different course role in the current course.
   user self-enrolling as a student

- furl has the symb arg appeneded to it

- id split backwards

- handle the case of non-browseable resources stuck into the middle of a course

- move absoltue_url to lonnet,
- use absolute_url in lonnet::ssi

- move to using a sub as more location are going to need fixing.
- navigation thorugh a course with https:// works

Bug #1223: error when first resource is hidden
Also: error when first resource is encrypted

- moved to the new LONCAPA pacakge

- start_page

- BUG#4692, trying to add a standardish way of adding form parameters to a url

Bug #4692: foo?register=1?symb=

- need to check if
  - I can get to the resource through a valid forward path (check the condition_ for the res)
  - and if I can is this link a valid one to take

- Apache 2 doesn't like it when PerlCleanupHandlers don't return an Apache::Constant (like OK or DECLINED ...)

- eliminating more $_

- BUG#4318, the use of $_ was screwing this up

- eliminating dead code

Better and internationalized messages

Escape symbs so + signs in filenames work

Return to Last Location also in Construction Space, eliminate stupid
"noidea.html" and go to Navigation instead.

- BUG#4259, forward/backward didn't work when the same resource occured in a row (now send symb along so as to get correct resource)

- make sure "What's New" shows up if it is supposed to

- BUG#3753, launch window now when launching and not knowing what the next resource is, will present a screen with links to first resource, and to close the external navmaps window.
- also more links in the navmpas window control the loncapaclient window rather than open in the navmaps window

- ENV -> env

- the _symb.db now actually does store symbs
- I am pretty sure the symbread changes are correct, but I still need to double check them

- more $r->content_type eradication

- back/forward work

- Yes, I am that stupid

- if the user is adv they should be allowed to step through hidden resources.

Accommodate case where we are moving forwards (or backwards) and encounter an empty folder, followed (or preceded) by a page. This situation can occur for a course structure created from an IMS import.

Version number is not part of anything in bighash except src.

- stupid typo
- removing the blind acceptance of the answers target as a form parameter

- an even better solution

- maybe this is better, should fix 2190

- mod_perl 2 isms

Hiding symb-splitting behind &decode_symb

Version 1.39 was not a good idea.

Along the lines of Bug #2049: $ENV{'form.postdata'} gets its data from a
piece of JavaScript, which also picks up the raw URLs.

Link logging, and installation of managekeys handler.

More informative message when reaching the beginning and the end of the course.
Also, make error messages text-based.

URLs to go to should not be pulled from the symb, since that will lack
query strings and public/wrapper prefixes.

* Start using library routines in lonuserstate and lonpageflip (ancient code)
* Have lontest show symbhash
* Have is_on_map filter for wrapper

Attempt to better catch and log untied hashes by usage of cleanup handlers.

Hopefully fixes Bug #1026 - climbing up more than one nested map level.

Corrects bug 825. Clicking next after selecting a choice from lonpageflip
now works, as the symb is no longer lost.

Bug 790

Recognize additional "native" resource URLs from uploaded docs.

Need to replace hard-coded "/res/" by call to lonnet::clutter.

Probably not all place have been caught yet, other routines might also
use a hard-coded /res/-prefix.

- i think the last of bug#574

No need to check for "allowed" here.

Skip over "randomout" resources.

Bug #175
If the beginning of a sequence is an empty resource, use "move" from
lonpageflip now to get to non-empty page.

Hopefully now also works the other way around

Hopefully fixed "forward"

Trying to disentangle the maps

Need to remember map in which we started

- typo fixed
- move last_known to be set earlier ($mapurl changes value after the move call)
- looks like BUG#270 should be fixed

Very broken now.

GPL

Handles /adm/wrapper and gives friendlier message and beginning and end
of course.

No more up and down - makes no sense

Go on with life after empty URLs

Hopefully flips pages across chapters

Parameter mechanism changes

Bug fix, should also set parameters if multiple next pages

Sets parameters for the next page

Return location implemented

REDIRECT not necessary if last known URL could be found

Work on user dialogues

Further work on flipping pages

If current location unknown, calls /adm/ambiguous.

lonuserstate cleans up symb table, lonpageflip contributes to it

Actually flips pages now for non-ambigous situations!

Slowly (slowly!!!) starting to make some kind of remote sense

Further work on lonpageflip

New handler to flip between pages (only does nonsense right now)
