Removed the translations of months and weeks from the Scheduler bundle
since they were already translated in Locale files.
- The a3_<month> strings were removed (replaced by
NSShortMonthNameArray)
- The months strings were removed (replaced by NSMonthNameArray)
- The weeks strings were removed (replaced by NSWeekDayNameArray)
Moved the a2_<weekday> strings to the Common bundle and added a new
method [UIxComponent commonLabelForKey:].
