[PATCH] Experimental patch view mode

[Piotr Piastucki <leech miranda gmail com>]

Attached is a set of patches that add an experimental patch view mode 
which shows changes included in the given patch file.
To start patch view mode run meld as follows: meld patchfile.patch
The first patch in the set, which adds proper editable states handling 
may be applied regardless of the rest as it may come in handy any way.
Here is a screenshot showing what the patch view window looks like:

This is a kind of proof of concept at this point so any 
comments/ideas/critique are welcome.

Cheers,
Piotr
