Bug Fixes
This update should address the issue that keeps cropping up where if you die the images do not refresh again on respawn. I had this done a long ago, but unfortunately haven't had a chance to get it finalized and uploaded.
In addition, this should address random errors that happen for certain people such as loading chunks asynchronously etc.

ProtocolLib Support
This update also adds support for ProtocolLib. By no means is it required, however, it can increase stability of the packet handling primarily used when deleting images.

Therefore, if ProtocolLib is installed on the server already along with CustomImages it will now be detected and used over the internal packet handling in order to increase stability.

Also, for plugins that are incompatible with the way that CustomImages does packet handling (there have been several such as when getting an error about PlayerConnectionProxy) using ProtocolLib would be a way to remove the incompatibility and be able to use both CustomImages and the offending plugin.
