Ship selection screen and bug fixes

Latest changes

I fixed some bugs this week that I found in the last play test a couple weeks ago and have moved onto working on the menu system.
Created a ship selection screen in charpad pro and then moved it into the game, this posed a few challenges to get working but managed to get it acting the way I want.

Added Spread fire to 3 player mode for the lone 3rd player to even out the 2v1 a bit. It is working fairly well

I intend to work on the main menu a bit for, highlight the active field and whatnot and add a way to get back to the menu from the Round Over screen. 

I am going to run another 3-4 player test this weekend to see if the bugs were indeed corrected and flush out any new ones.
