- added mesh_strip_loose_faces, works in conjunction with make_edges

Browse Source 
to get rid of faces with MFace.v3==0
 - change all Mesh's to have ->medge now. This is forced by make_edges
   on readfile, and in the various exotic important routines, and on
   conversion back in python.
 - make python NMesh structure always have medges now (needs testing)
 - with above two changes it is guarenteed that mf->v3 is never ==0
   in main blender code (i.e., all MFace's are actually triangles
   or quads) and so I went through and removed all the historic tests
   to deal with MFace.v3==0. Equals lots of deleting, I am in heaven!
 - removed MEdge edcode flag, no longer needed
 - added experimental replacement for edge flag system

Still are some inconsistencies in FACESELECT mode edge drawing to
be ironed out.

NOTE: This commit adds an experimental edge flag calc system, based
on 10-seconds-of-thought algorithm by yours truly. Would appreciate
feedback on how this system works, esp compared to old one and esp
on complex or interesting models.

To Use: New system is enabled by setting G.rt to a value between
1 and 1000 (Value of 0 uses old system). Value 1000 is reserved for
"auto" edge, which is more or less identical to old system but also
makes sure that at least 10% of edges are drawn (solves errors for
super subdivided meshes). Values between 1 and 999 act as percent
(out of 1000) of edges that should be drawn, starting with "most
interesting" edges first. Please try it and comment!
