Extended unit test.  It is currently failing - I think the issue is the
int rounding describe in islandutils.
Found the core error.

Negative values...
Fixed te getLocalX and getLocalZ methods for negative values
Added new tests, which actually work.
A test for islandName.
Made inner clases public.
Registered source code for my own personal use, stolen from a comit
somewhere.
IslandInfo work.
A command that overrides the vanilla USkyBlock command.
Actually, it might make sense to have it not be preprocessed.  
Instead, it would remove the old one, and then extend on its
functionality.
