#8 Some more filters for the overview

[Stefan]

I would appreciate if there where some more "default" filters that could be set with one button:
- Complete months
- (one button for February, March, April, May, June, July, August, September, October, November, December, January)
- the last month would be the actual month
- Complete quarter (Q1, Q2, Q3, Q4)
- one button for each quarter (Q2, Q3, Q4, Q1)
- Complete year (actual year plus 2 last years)
- (one button for 2009, 2010, 2011)
