Add a fish permission

[FireML]

Adds the ability to lock fish behind a permission.

    Shiny Pickle:
      permission: "emf.shiny_pickle"

This fish can only be caught if the player has the emf.shiny_pickle permission.

It loops over all possible fish until the player has permission, or all fish have been checked.

If the player doesn't have permission for any fish, it prints an error to console:

[10:13:39 INFO]: [EvenMoreFish] [STDOUT] Max: 1
[10:13:39 INFO]: [EvenMoreFish] [STDOUT] Checked: 1
[10:13:39 ERROR]: [EvenMoreFish] Could not determine a fish for FireML. The player doesn't have permission to catch any fish! (See fish.yml)

Thank you for the contribution, however I think this overlaps with the permission requirement in com.oheers.fish.requirements, or does this work slightly differently and if so it may need renaming for clarity.

oh so it does. i didn't realise it already existed, my bad.
