New Style option: Overlap

If this option is enable, the blenfont check for overlap characters, like
one of my previous commit but now it's optional and disable by default.
(This fix the "Fi" or other case when the characters are too close)

Enable/disable from:
Outliner -> User Preferences -> Styles -> Panel Font -> Overlap

(also for other styles, Group Label, Widget, Widget Label)
