add all staffs and their functionality

[GabeHasWon]

Description of Work

• Adds in 7 Staff variants:
  1. Copper Staff
  2. Iron Staff (normal charge time) - NC for short, lvl 5
  3. Lead Staff (longer charge time, higher damage) - LC for short, lvl 5
  4. Silver Staff - NC, lvl 12
  5. Tungsten Staff - LC, lvl 12
  6. Gold Staff - NC, lvl 17
  7. Platinum Staff - LC, lvl 17

Staffs charge up a projectile which can be held indefinitely and fired in any direction. They are much stronger than Wands but usually slower and more deliberate. Staff alt use decreases the charge time for all of these to 1/4th of normal time for 2 seconds and automatically fires them, allowing for a sudden burst of damage.

…and yes, I did forget Tin existed.

Added multiplayer compatibility as I realized I didn't test that properly. Works perfectly in MP now, and also touched up behaviour in singleplayer as well.
