Added unit builders - all units now wait until end of turn to 'deploy' and grant vision

Also bumped version number
Slight balance adjustment for the mech
Added 'artillery' unit and 'sightrange' property (defaults to attackrange)
Added splash damage, converted VERSION to String, bumped version number
Bugfixes - still had some trouble with version errors, also splash damage was applying to out-of-range attacks
Moved center towers farther apart on test map, bumped version number
Implemented a quick and dirty ability indicator (click to toggle) in the info bar to allow stealth and detection
Added very simple reconnect logic

Right now, upon disconnect, the client that disconnected pauses and attempts to reconnect.
The server sends a pause and waits 5 seconds for reconnection before delcaring the remaining player the winner. Right now there is not a mechanism to ensure that the clients are still in sync - need to do this!
