This version of SubServers.Client has the same features as the Bukkit version, minus the chest interface.
This feature may be added in the future once the documentation surrounding chest interfaces becomes more thorough.
This commit changes the way SubServers.Host launches itself and loads it's plugins. Overall loading plugins this way is more efficient, faster, and can cause less problems than before.
Plugins will still use the package.xml & @SubPlugin annotation system to be loaded.
Also, there are some changes to the logger that better support async logging.
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.
