[Request] allow gm to set permission to allow players to create/modify effects

[Mizzajl]

I have tried giving my players full permission to everything but they still cannot create/modify or duplicate as custom for the effects.

[DFreds]

Ah, this is an interesting issue. It's because the underlying item that holds the effects probably doesn't have player permission. The item is automatically hidden in the items directory.

I added a new setting to fix this: https://github.com/DFreds/dfreds-convenient-effects/wiki/User-Guide#allow-player-custom-effects

Should be out in the next minor release
