Fix:
[#25834] no color of textobjects in game engine when combined with
textured objects
[#26893] Curruption of displayed text (debug properties/fps info or bgui)
when using animated/tile uv mode

The first bug was beacuse a bad mode on the texture environment, now
we save the current glTexEnvi, set the one that we need, draw and
restore the original at the end.

The second was because a missing call to glLoadIdentity for the
texture matrix and as we do before, now we do a gl-Push/Identity/Pop
for this matrix to.

The first problem was solved by Kanttori and the second by Dalai.
