[MonoDevelop] managed dock

[jeroen@xs4all.nl]

Cool dude!

So i assume it's no longer unstable when you dock/undock items? Previous
code (perhaps gtk# was the culprit) has a random crash where the GC tried
to collect something that was already destroyed/disposed (something like
that).

IIRC this problem showed it's head after redocking and waiting for the GC
to activate.
