Merge pull request #1 from timj11dude/master

Super secret fixes.
- Added world delete to Unloader.
- Worked around a bug in Bukkit where re-using the same name for a world meant it did not load in a clean copy of the world. Worlds Loaded now are a named for a random UUID that has not been used yet (Not sure if that check was redundant) Reloading extra times in a session uses a new name.
