Bug#806212: monodevelop: Program will not start

[Jo Shields]

It's unrelated. MD needs a version update to work properly with Mono 4.0 
(and 4.2). Generally, MonoDevelop releases happen in sync with Mono, and 
they should be upgraded in lockstep (MD 5.10 for Mono 4.2).

I haven't yet done it for MonoDevelop, as there's a bunch of peripheral 
work that needs doing, which is not so easy to resolve. But I should get 
it sorted in the not too distant future.
