Created a new move array called CUSTOM_SKILLS. This array is used to add moves that can be used through the party menu that have custom effects. The following moves are included by default, with their effects already present within the plugin (thanks to TechSkylander1518 for the base scripts for these effects).
Instruct - Allows a party member to relearn a past move.
Sketch - Allows the user to Sketch a party member's move.
Future Sight - Allows the user to see the species of an Egg, or next evolution/move of a Pokemon.
Added a plugin setting named CUSTOM_SKILLS_REQUIRE_MOVE to allow you to toggle whether or not a Pokemon needs to know a move found in the CUSTOM_SKILLS in order for that move to appear in the Pokemon's skill menu.
Added a new script in the plugin folder named Party Skills that contains all code related to skills that have a direct use within the party menu, rather than performing an action within the overworld. By default, this contains all the code related to HEAL_SKILLS and CUSTOM_SKILLS.
