Basic network manager script. Gives the buttons to create and join a server. Need to make the object stick around when the combat loads.

Also needs to actually send stuff back and forth. Will probably start with a simple RPC call to test. Then needs to be able to send latest gestures back and forth.
Basic network manager script working. Able to connect between tablet and PC. Although there are sometimes issues with NAT.

Currently displays a big refresh banner when refreshing. Should do the same for when connecting. Also need to make it so that
better errors are displayed when it fails to connect or when the server disconnects.
Added a scene for combat. Currently just displays the working Combat HUD image from the dropbox.
NetworkManager now kills itself when reentering the main menu. Before multiple NetworkManagers would be spawned when reentering the menu.

Can connect on same machine and draw gestures on both, but the RPC calls between the two are not working.
Saw some gestures sent back and forth. Not perfect, but definitely have some networking stuff working.
Can remotely draw stuff between tablets.
