Blender Git Loki

Open recent list was arseabout, only adding files on save, rather then open.

This is problematic for a few reasons...
* I'd often save a blendfile only so it would appier in the open recent menu.
* Saving files (when you dont need to) makes access times less useful.
* binary diff's in SVN dont give any useful info. Sometimes I wasnt sure if I actually edited or saves for fast re-opening.
* Testing 2.4x files with animation data in 2.5 can loose info.
* Its not logical and other apps dont work this way.

Also made the recent file list in the file browser display the most recent item first (like the open recent menu).
