Player Weapons

[joshheinrichs]

Melee and ranged weapons. We don't have to decide on what they are yet really, just make them squares.

It might be a good idea to make some sort of Damagable interface that applies to players, enemies, etc so we can generalize damaging characters.

no weapons yet for the player, but projectiles can now do damage to the player instead of kill on hit, and enemies can melee the player. See 518214dd78a660557d4f0647baab2cf47f34fab0

Added a projectile weapon for the last milestone, probably won't add melee weapons
