Finished Hangar framework

Updated hangar, so you must select your desired weapon and then hit
"Start" to begin the game with it.
To Do:
-Add statistics view to all weapons for user GUI stats
-Fix where the "Start" button is and the texture and stuff
-Add more weapons into EnumWeapon
-To craft, add ability to hold more weapons
-Limit weapons holdable to 6
-Fix the TaskFire on the Enemy (in GameState.enter), because it breaks
when there is no weapon.

Later:
-Add algorithm to randomize/make fair the weapons given to the EnemyShip
