New export possibilities for co-worker reports

There are new CSV export possibilities for co-worker reports:
- Export of the absence calendar (in addition to the ICS calendar export)
- Export of the key figures for work times, holidays and sick days
- Export of the exact work time lists
For the export of the work time lists, there are some additional features in order to be compatible with your accounting software: For holidays, sick days and nonbusiness days completely fulfilled planned hours (e.g. 8 hours) can be exported instead of the worked time »0«.

You'll find the new export functions at the very bottom of the absence calendar, respectively of the co-worker reports and its overview page.
