[MonoDevelop] Monodevelop statusbar enhancements...

[Jae Stutzman]

I use VS.NET at work if you double-click the status bar in the cursor
area it pops up the goto line dialog, and the INS/OVR area causes a
toggle of the behavior.

I've been playing around with 0.1 trying to get used to the code
structure and thought I'd see what it would take to do something
similar. Well I've got the events all going back to
SourceEditorDisplayBinding.cs but am having trouble with the
ToggleOverwrite event...I can't find a way to trigger it from the
outside. If there is a way, does anyone know? Also if the only way to do
this is to simulate a keypress, then maybe the gotoline should be done
similar. If that is the case an example would be helpful.

Don't know if this is a desired feature or not, but I'm trying to learn
some on the gtk# (coming from SWF world). I'm keeping track of stuff I'm
changing so a patch can be made later.
