Changes to allow python to do redraws through the timer operator, a reliable way to test the overhead of the python api (printed to the consoel on exit).

- rename WM_OT_ten_timer to WM_OT_redraw_timer
- added iterations argument to run more then 10 times (10 is default still)
- use report api rather then always calling a popup directly.
- added a new test that draws every region without swapping.
- dont show the info popup when operators are called from python.
- operators called from python now print reports, useful with the interactive console.

 eg. 
>>> bpy.ops.wm.redraw_timer(type='DRAW_WIN', iterations=300)
Info: 300 x Draw Window: 4168.56 ms,  average: 13.8952
