Code further debugged and implemented methods for chat formatting

Many classes have been edited, and I have been working hard to 
get up to this point. Please note that this plugin is still not
ready to be released and many commands do not work. Still figuring
out how to store data.

TODO:
  - Implement documentation (CRITICAL)
  - Fix /sf add, /sf remove, /sf accept, and /sf deny (CRITICAL)
  - Release a stable build of SimpleFriends to BukkitDev (Important)
