Tested Controller compatibility (oops)

Improved controller compatibility
Added config:
- Invert mouse buttons

Tweaked rotation mode for Teardown 0.9.3+
Added effect config:
- Object outline
- Beam
- Freeze/Unfreeze effect
- Tool Model
- Sounds

Added workaround for maps that use an explicit static body as the world.

Updated for 0.9.3
Added new rotation mode (avoids showing the cursor when spinning a prop)
Added config:
- Legacy rotation mode
- Rotation speed
- Basic keybinds

Added extra safeguard against mods which call SetToolTransform when they shouldn't.

Updated UMF

Reintroduced game.input.locktool in tool locking which was accidentally removed when updating UMF.
