Transform goodies;

- Added icons for the Widgets to blenderbuttons pic
- Added in header - if widget in use - three buttons to choose widget type
  (hold shift for combo widgets)
- Hotkey CTRL+space now switches widgets on/off

I also noticed negative scaling doesn't work satisfying yet;
- for scale widget, using center didn't work correct anymore (fixed)
- negative scaling didn't even get applied! (fixed)
- but; scaling somethig negative now flips back to positive... ????

Last one i need Martin P for! Note that I had to change Mat3ToSize....
