jrbudda tweaks v2

• Add shift (sneak/dismount) button to L Controller grip button
• Split L Controller touchpad button into 2. Top half is inventory, bottom half is jump.
• Fix drop item on R controller appmenu button.
• Holding down R Controller grip for 4 seconds toggles free move mode on/off (this is temporary)
• Free move mode defaults to LController driven since most people prefer this.
• Increase sprint window, possible but tricky to sprint in free move mode. Kind have to play with it due to the inertia setting minecrift introduced.
• First pass at balancing arc teleport. (this will all be optional eventually)
  • No changes to length or cooldown yet.
  • In survival mode, can only teleport if the arc lands on the top surface of most blocks. You should easily be able to climb 1 block standing next to it, 2 blocks if you're tall enough.
  • Ladders can be teleported onto. (little buggy still, but climbing is possible)
• Probably maybe fixed boats and carts.
