This commit removes the org.JSON library where alternatives are already provided (Bungee & Bukkit provide Gson). This change was made to improve compatability with BungeeCord plugins and reduce file sizes.
This means big changes to the SubData API, which heavily relied on org.JSON. Now we submit our data through YAMLSection to be converted and sent over the network.
SubServers.Bungee can now link servers to subdata clients via connection address and port number.
Since this still has the chance to fail, the `Name` field will appear if no servers were found this way, and will be used the same as before. SubCreator made servers will still have the `Name` value present and filled out for assurance.
This marks the beginning of SubServers.Host. As of now it is just a
simple plugin loading API, but it is planned to become a way to host
servers on other machines.
Also, SubAPI now checks to make sure variables aren't null in many
places.
