partially implemented core functionality
Finished Implementing core functionality

Made wildportal command actually work--however it uses a hard coded
(x,z) range of (-314 to -151, 70 to 250) at the moment. The Listener has
not been known to work yet (exclude ClickListener.java or it probably
won't work) and only one sign is allowed, hard coded at (x,y,z)
(-142,80,263).
