Update v1.1b

- Added the Perk-a-cola machines & PaP, with the tool - However, only
Juggernog functions, unless the server owner provides functionality
according to their weapon pack. (See config.lua)
- Added the basis for the zombie links (But is not functional)
- Cleaned up a few things
- Some other stuff I forgot to document
- This is a (kinda) beta release, as this is the update prior to waiting
for the actual GMod update that adds the GM:EntityFireBullets hook,
which is required for the PaP to function.
