Shift-right-click to turn an item frame invisible/visible

Requires invisibleframes.toggleframes permission

Config:

Defaults:
lock-frame: true
toggle-empty: false
blacklisted-items: []

Lock Frame:
lock-frame sets the item frames to locked when they are invisible, stopping the items from being able to be knocked out, and having a random invisible item frame you cannot see

Toggle Empty:
toggle-empty allows the item frame to be toggled when empty. This is off by default so as not to have random invisible frames everywhere

Blacklisted Items:
If an item frame contains an item from 'blacklisted-items' - it will not be toggled. This can be useful if you have custom items that use invisible item frames. Items must be declared how they would be written in a vanilla /give command ( "minecraft:iron_nugget{CustomModelData:1234}")

NOTE: Itemsadder is supported, if you have custom items through itemsadder, you do not need to add them to blacklisted-items. The item frame will already not change state.
