Disable NPOT check to keep GL 3.2+ from crashing

I didn't expect adding the SOIL sources to the egg would pay off so quickly!

As it happens, SOIL crashes badly when you try to use it with GL 3.2+ due to a failed non-power-of-two capability check. This patch disables the check entirely, since I couldn't figure out how to properly do the check without making larger changes. Pretty much any graphics card that's still running should have this capability, though, and the ones that don't shouldn't (I hope) crash so badly when non-power-of-two textures are used.

Additionally, I incremented the version to 1.2.1
