* Big, mundane clean up and edit of (error/ok/etc)

messages and pupmenu()s. Edited spelling and grammar,
 stylistic consistency, etc.

I added the guidelines and rationale that I used to the
 CMS here:
http://www.blender3d.org/cms/Language_and_terminology.338.0.html

Next step is to get icons in there, to make it easier to see
 at a glance what sort of message (and how much attention
 should be paid to it, or if it can be dismissed with a flick
 of the mouse, eg. boring remove doubles notifications)
