[CGMZ] Skill Equip - Version Alpha R2

Hi all, today this plugin was updated to version AlphaR2!
This version adds always equipped skills. These are skills that are counted as equipped, cannot be unequipped, and do not count towards the maximum equipped skills. They basically exist separately outside of the skill equip system.
This update also adds the ability to lock (and unlock) equipped skills. If you want to force the player to have Ice Storm equipped for the fire dungeon, you can now do that and make it so they cannot unequip that skill. Unlock the skill once you are ready to allow the player to unequip the skill later.
A plugin command to unequip skills was also added.
- Added skills which are always equipped
- Added locking and unlocking equipped skills
- Added unequip skill plugin command
