HEAD
In process of removing remote control, remote navmap and different icon modes code
- removed no_inline_link argument from loncommon::start_page, loncommon::bodytag
- removed subs
o loncommon::head: it wasn't used
o loncommon::endheadtag: functionality now covered by loncommon::headtag
o lonmenu::registerurl: functionality moved to loncommon::headtag, because it was the only function that called registerurl
- removed remote control related translations in de.pm
- refactoring and cleanup
