New: Fake Polygons, or Face-polygons, or FGons nicked for now.

Browse Source 
Just select a bunch of faces (selection should be valid flat poly) and
press FKEY. Works in fact as selection-group optimizing. Nice in solid
drawmode!

Further some small additional fixes in the whole debugging process.
Found old error in loopselect for triangles, subdivision code, and
selection still.

NOTE: subdivide still works on vertex level only.
