initial commit on Journey's Continue branch, adding some basic staff …

[VariianWrynn]

…and a demo weapon

[Setnour6]

Concerns:

• There doesn't seem to be a staff added, only the rampage charged gun.
• The gun spark and rampage bullets do not appear.
• There is no shoot sound for the rampage charged gun.

Changes requested:

• Stamina/Charge Bar is offset from the player by a lot, and should appear close to the player.
  
  The stamina bar is on the tree with the pink leaf instead of near the player.
