HEAD
Optimized status bar localization:
Overhauled status text creation to allow proper translation.
- Translate whole sentence instead of unhandy phrase fragments concatenation.
- Simplified way of time text creation by using quant.
- Removed code for not anymore supported old browsers (bug 1382).
- Indirectly corrects mt() call with incorrect parameter (_2 -> _1)
