Patch from Tom Musgrove to bypass extrude popup on singular selections...

Implementation had some issues though, since:

a) Blender has no stats available that tells amount of selected edges
b) Bypassing the popup should be 100% accurate
b) Once you do that, the popup should actually only show possible
   choices as well.

So! I've added a G.totedge and G.totedgesel, also being printed in the
info header. Using this variable the extrude popups could be limited too.

Also: made 'normal alignment' for edge-only selections work when the
normal wasn't pointing OK. Now it aligns the Z axis with the edge itself
Exact algorithm for choosing a 'normal' and 'plane' still is weak.
