remove properly [[context]] strings from translated messages
src/Messages.cpp: general cleanup. (cleanTranslation): remove [[context]] strings from a docstring. Use plain string manupulation instead of regular expressions. (get): use cleanTranslation also on strings that got translated. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@21641 a592a061-630c-0410-9148-cb99ea01b6c8
