Spoike bae63427a5 Desperate attempt to boost framerates with webgl. 
Models now use static vbos, because we ought to. Yeah yeah, extra memory usage etc.
Reduced size of streamed ebo by reallocating on each mesh. Hopefully the browser won't scan so much memory now.
Reordered attribute indicies in an attempt to comply with possible absurd gl behaviour that emscripten warns about.
Fixed an issue with if statements in shaders.
