Weapon in hud

worth taking a look at as far as UI

SELECT + UP cycles your weapon to the next

SELECT + DOWN deselects your weapon (so you can punch)

if a wieldable is in the HUD window, the next time you attack the attack button takes out your weapon (@jhoff, let me know if you additionally still want it to wield['tis but a small change])

if it's a projectile in the HUD window, the next time you attack it shoots a projectile
