TeaWaystones

I rewrote a lot of code in this release.

• Waystones are now only read from the file once when starting the server - now the waystones get saved to the file only once (when the server shuts down)
• Waystones are now sorted by their names.
• some crashes have been fixed
• fixed empty spaces in waystone menu

spigot and craftbukkit are currently not supported due to an incompatibility with paper text coloring
