Add distant horizons support

[Alex_Danov]

Now that distant horizons is available as a plugin for bukkit based servers might as well add it.
I am sure it won't affect tps or server performance that much. After all it is a client side heavy mod, needing the server to only send a few packets of the terrain map or whatever for the rendering.

Would love this but only if it doesn't impact performance too much. seen soem discussions around it having alot of issues when people need to load new chunks which means that the world border could become interesting at each expansion as we might end up with hundreds of chunks beyond the border already being loaded.

We are really busy with dev and admin stuff, but we can explore this in the future!
