BGE: TexFace panel (from patch #21780 from Mitchell Stokes + some changes)

the patch exposes a rna property to get the active edit mode face. This is a hack.
However it's a small patch (a.k.a. easy to revert later if needed).

The official plan is to wait for BMesh before tackling it properly. Nevertheless TexFace panel is really important for BGE.

Missing: operators to copy the current parameters to other selected faces.

* note: what I changed from the original patch is the UI script. The pool wasn't defined and it was using tabs.
