Formatting, Configuration fixes, cheat protection redesign

For the formatting, I used 'Bukkit-Tabs', which is the same as the Bukkit project except using tabs instead of 4 spaces.
The only difference is that it's impossible to enforce 1-line blocks always having braces in the Eclipse formatter, so those were left alone.

Home, Station, and Flight were made ConfigurationSerializable to simplify the load/save code and centralize it in the class itself.
The config files are kept compatible with previous versions.

CheatProtectionHandler has moved the actual calls to the AntiCheatHandler and NoCheatPlusHandler classes, with a AbstractHandler interface behind them (should it be renamed? meh.)
