Made the code tidier and also made it easier for other mods to do something with it.

Fixed someting else from a few seconds ago.

Fixed 2 debug messages being left in.

Changed the code to improve it and make making a mod using it easier, fixed a problem with loading aluminium bolts, fixed a glitch that has been there for a long time that was caused by having a "." instead of a ":", fixed problems with unloading, reduced the effect of the reload skill on how long it takes to reload a crossbow.

Cleaned the code a little, fixed a thing or two, added shooting pencils from crossbows.

Added options for loading different sorts of bolt to the right click menu for crossbows.

Added aluminium bolts that you can find with the steel crossbow, that have a bit better durability than pure wood ones.

Increased XP from reloading crossbows.

Fixed not getting bolts back from zombies because of a mistake in an update to this mod.
