RPG Maker DoubleX RMMV Permanent States v1.02b

*  # State manipulations 
*  1. meta.permanentStates 
*  - Returns the permanent state scenes and types in 
*  <permanent state: scene, type> in the form of 
*  { battle: types, map: types } with types being an Array storing
*  all unique String type or an empty Array if scene matches and 
*  doesn't match the property name storing types respectively 
*  2. meta.permanentStates = [scene, types] 
*  - Sets the permanent state scene and types in 
*  <permanent state: type> as { battle: types, map: types } with 
*  types being an Array storing all unique String type which will be
*  used in the scene matching the property name storing types 
*  - All meta.permanentStates changes can be saved if 
*  DoubleX RMMV Dynamic Data is used

*  # State Notetags: 
*  1. <permanent state: scene, type> 
*  - scene can be either battle or map, meaning the state can be 
*  restored in battle or map respectively 
*  - type can be either persist, recover or revive, meaning the state
*  will be kept upon death or recover all, or added back upon revive
*  respectively 
*  - The same state can have more than 1 permanent state scene/type
