lok: form controls: rendering and mouse event forwarding

What we got
- Most controls rendered on Writer and Impress (on Calc already
implemented by Tomaž Vajngerl)
- Text labels rendered correctly
- Mouse events forwarded to controls
- Control state changed on click for Writer and Calc
- Control invalidation for all apps
- Fixed broken LOK_CALLBACK_MOUSE_POINTER msg
- Correct pointer style when mouse is hovering over a control

Need to be improved
- in impress click method for a control is not executed even if the
mouse event is forwarded correctly
- avoid not needed control invalidations (as the one occurring on
document autosaving)
