Add option to draw orient lines on selected object

Rotation editing improvements

- Added optional in map editor menu to rotate bounding boxes based on the objects orient field. Useful for objects that don't have meshes in NF like player spawns.
- Re-enabled the orientation matrix in the editor in case its needed. Put in a collapsed header under the pitch/yaw/roll sliders. Also lets people make cursed maps by fucking up the matrix if they want to.
- Added button to reset the orientation matrix back to the 3x3 identity matrix. The pitch/yaw/roll sliders math seems to have a problem since if you do a bunch of rotations then return the sliders to 0, you don't end up with an identity matrix again. Maybe need to apply the rotations in exact reverse order. For now this will suffice.
