Localization, wording, nobreaks for Colorful Editor
- Added missing &mt() calls at several places (more to be done)
- Same wording "Delete?" for all Delete options
- Same wording style, e.g. added ":" after text and before optionlist
- Added nobreak style for some elements which need to stay together, e.g. help_open_topic in loncommon.pm
- Added/updated some related German translations

=item &whichfoils($max,$randomize)
Randomizes the list of foils.
Respects
- each foils desire to be randomized
- the existance of Concept groups of foils (select 1 foil from each)
- and selects a single correct statement from all possilble true statments
- and limits it to a toal of $max foils
WARNING: this routine uses the random number generator, it should only
be called once per target, otherwise it can cause randomness changes in
homework problems.
Arguments
$max - maximum number of foils to select (including the true one)
(so a max of 5 is: 1 true, 4 false)
$randomize - whether to randomize the listing of foils, by default
will randomize, only if randomize is 'no' will it not
Returns
$answer - location in the array of the correct answer
@foils - array of foil names in to display order
