Rewritten and repackaged a bunch of the internals of the plugin.
Removed an unneeded soft depend.
Added missing description and website link in the plugin.yml that shows on /ver
Added a /ITF Scan (Radius) command that will find any item frame within the radius and spawn particles at visible and invisible item frames for 6 seconds, mostly for use when you cannot find an invisible item frame.
There are some config changes so please regenerate your config if you want to edit them but upgrading from v1 is no problem.
