CVS tags:
HEAD
Optimized and enhanced confirm messages:
(currently only used in lonpreferences.pm)
- Introduce new sub routine "confirmwrapper" and related style "LC_confirm_box"
Wraps option changes confirmation messages in a box (better separation from rest of screen)
- Moved trailing confirm icons (success/error) to begin of the confirm texts
- Added confirmwrapper to preference settings; consistent output (removed some br, hr, etc.)
- Added HTML new line codes ("\n") to lines in &confirm_success
Localization and Wording:
- Optimized &mt usage und optimized localization file usage:
Re-use existing phrases and always use same structure of messages ("Set [_1] to [_2]" and "Reset [_1]")
- Optimized wording (eg., Screenname and Nickname)
- Some optimized/corrected German translations and removed now unused phrases
- Optimized confirm text output for author option: "Block access to construction space"
