fix for non Euler-XYZ rotations...

- Camera to 3D view didnt check for rotation order.
- Fly mode didnt check for rotation order.

added util functions.
- object_apply_mat4(ob, mat4); applies a 4x4 matrix to an objects loc,scale,rot (accounting for rotation modes)
- object_mat3_to_rot(ob, mat3, use_compat); apply a 3x3 matrix to the objects rotation, option to use a euler compatible with the existing euler.
