take delta's into account when applying the objects matrix (dloc, drot, dsize).

Now object_apply_mat4() can be used as the reverse of object_to_mat4().

Noticeable result is fly mode and 'Apply Visual Transform' dont jump when deltas are used, also means setting matrix from python works as expected.
