[MonoDevelop] Suggested change to navigation drop-down behaviour

[Mike Krüger]

Hi

I've just committed my 1st version of the navigation drop-down successor.
I could need some input on the new version. The problem I had with the 
old navigation drop down was mostly that it took too much space. It's 
likely that we'll need that space above the text editor in future versions.

The 2nd problem was that it wasn't really good showing inner types / 
regions ... I hope the new solution is better.

I could really need feedback & ui suggestions for the navigation drop down.

Regards
Mike
