Updated between Robert's, Sam's, and my scripts.

- Multiplayer works in this version.  Single player is broken due to the
change in how information is stored between scenes.  Can access single
player by running a multiplayer game as host by yourself.
- Some aspects work on either pc or tablet.  I might have broken
something but the dino select doesn't work on pc but it does on the
tablet.  The tablet also has some issues transitioning into the game,
doesn't always remove the menu ui.
- You can load different dinos and control them.  Controls are pc only,
believe I broke something there but the tablet can select different
dinos and load the different types accurately.
- Position of racers is synced.  The dino animations are not.  Due to
the use of mecanim I have to run RPCs to get the animations to sync up.
Network views can observe animation components but not the animator
controller component mecanim uses.

Just a warning, I played with a lot of different scripts to get this
working.  Haven't looked at syncing VFX yet and since we're still on
transform version of the motion controller it still has some issues
going up and down slopes.  Hopefully John can get his rigid body
controller working.
