WorldBorder as lightweight library/utility

I'd like to use WorldBorder in my plugin as a lightweight way to set borders and change them on the fly, for things like tournaments and games and stuff. To that end I've made some changes that would allow WorldBorder to be included as a library in my plugin, and operate that way. It was very easy, with the static architecture, and I only had to make a few small tweaks to get it to work. 

The code to include WorldBorder in your plugin then looks something like this: 

````java 
    com.wimbli.WorldBorder.PluginlessConfig.load(this, true);
    com.wimbli.WorldBorder.PluginlessConfig.setBorder("world", new BorderData(0, 0, 50, 50, false));
````

Does this look fine to you?  I've tested both plugins separately and they seem to work. It'll get messy if they're both on the same server, but nothing more wonky then having two simultaneous BorderCheckTasks running, due to Maven Shade.
