Remove shader Matrix transpose

[Daivuk]

This will changes pretty much everything. We need to change the order of Matrix's members.
Currently, we have to transpose everything we pass to shaders.
Now, when loading some from assimp, we have to transpose into our space first, then transpose back into shader.

This was pointed out by a user on last game jam.

Need to investigate. If we don't transpose anything at all, it might just work. But then run into issues with OpenGL?
