2.5

Render back! And not only back, even full threaded now. :)
Current state is unfinished, but too much fun to not to
commit for review and test!

WARNING: because render is in a threaded job, it will
use data as can be edited in the UI. That'll crash in many
cases of course... the idea is to limit UI usage to viewing
stuff, especially for the Image Window to inspect layers
or zoom in/out.

What works now;
- F12 render (no anim)
- ESC from render
- ESC pushes back temporary Image Window
- Render to ImageWindow or full-screen.
- Executing composites, and edit composites after render.

Note that the UI is 100% responsive in a render, you can 
switch screens, slide area dividers around, or even load
a new file during render. :) It's quite stable even.

I'll collect all crash reports especially to get a good 
picture of where the protection is required at least.

Also added: XKey "Delete Objects", to get things crash...
unfortunately it didn't for me.
