Updated to work with Love 0.9.0

This will no longer work on 0.8.0... probably.
Updated conf for 0.9.0

Always have to forget something
Switched from TCP to ENet

Also updated LUBE
Now with 99.9% less bandwidth!

Added: Players now have extra variables that determine if they are
moving/rotating and in which direction
Changed: Server and Client now calculate position without sending tonnes
of data back and forth
Changed: Server and Client now have (and use) their own send wrappers
Changed: Server has been given more power, as opposed to clients. If a
client is modified, it should not effect actual gameplay--cheating
should be more difficult
Removed: weird vsync-like code that I didn't use anyway (just use
vsync!)

TODO:
* Server and client need to calculate collision, collision no longer
works
* When a player stops moving or rotating, the server needs to send their
idle position or rotation to ensure all clients are in sync
* Bullets needs to be removed from the tanks, this was a bad idea I
forgot to fix ages ago
