* User preference to select with the left mouse button

instead of right.

This basically swaps left and right, in most window spaces
so you can choose between:
LMB: Cursor/time slider/paint  -  RMB: Select
or LMB: Select  -  RMB: Cursor/time slider/paint

Aimed at:
1. Newbies
2. 1 button mouse mac users
3. People like me who are sick of having to constantly keep putting their brains into different modes when
 switching between other apps and Blender :)

Yes, the User Preferences window is a bit of a nightmare
now, a layout cleanup will be forthcoming soon...
