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
