I fixed a few minor issues, added some internal stat tracking (to be exposed later), and updated the demo to have the new room/gloves.
- Fixed mounted artillery car snapping to itself.
- Added remote control panel summon button to toolbox.
- Modified the tutorial to use new control panel summon button.
- Added item delete step to tutorial.
- Fixed potential issue with track placement during tutorial.
- Made the remote control panel available when not riding a locomotive (in a railcar or on a station platform). Point at a locomotive and press the menu button to summon.
- Added stat tracking (spawn counts, meters ridden, etc.).
- Fixed hidden eject handle in double porter locomotive.
