Started work on guns

Started work on guns, mainly modifying core.java to transfer later.
Fixed text & added ammo to shotgun

Shotgun should now use redstone as ammunition.
Added ammo for shotgun

Shotgun now consumes (redstone) ammo to fire.
Added guns source code

The REAL good guns source code, that WORKS. Also customization and
stuffz. :D
Moved guns source to logical place

It should still be in the plugin though! Git will register tons of
deletes because I moved the files to a more native place for them. :D
Started migrating guns from own file into CardWars.java

Basically I started migrating onEnable and onDisable etc from the main
from Guns into our main at CardWars(.java)
