Delete SpiderTank Scene
Dumb change.
Modified all of the initial setup and systems
(see below)

Major Changes to the WeaponSystem
     _ name changed from "WeaponManager" to "WeaponSystem"
     _ much simpler and easier to use
     _ uses weapon prefabs instead of weapon names that are cloned from a master list
     _ all weapons can have their own behaviors and are all MonoBehaviors
     _ added two different gun weapons - a Pistol and an AssaultRifle
     _ the Player can switch between weapons via input
     _ weapons float next to the player model

Tweaked the DamageSystem to account for the WeaponSystem changes
     _ now just as simple to use on weapons as it was on characters

Modified the Enemy Systems
     _ removed the over-arching Level script
     _ the EnemyManager is now a simple EnemySpawner and is much easier to use; however, some more advanced features are still unfinished

Modified the Player Systems
    _ CardinalMovement and LookAtMouse removed, but combined into one PlayerMovement script
Merge branch 'master' into iss#9
