Updated SDL, Bullet and OpenAL soft libs

Fixed case sensitivity problem
Fixed clang compiler problem with having the class namespace used in an inline for the == operator
Tweaked some theme stuff to be more consistent.
Added initial test of no-pie for linux
test sidestep of getTexCoord in shadergen hlsl feature so we don't assert when getting the terrain's shaderstuffs(which uses float3 instead of normal float2)
