RPG Maker DoubleX RMMV Reverse Input v1.00b

 *  # Actor/Class/Equip/State Notetags:   
 *  State notetags take the highest priority, followed by weapon, armor,  
 *  class and actor   
 *  1. <reverse input: proto, downUp, rightLeft, pagedownPageup, okCancel>
 *  - This notetag only works for windows assigned to 1 actor at a time
 *  The below prototypes in default RMMV setting meet the condition:
 *  Window_SkillType.prototype   
 *  Window_SkillList.prototype   
 *  Window_EquipSlot.prototype   
 *  Window_EquipItem.prototype   
 *  Window_Status.prototype   
 *  Window_ActorCommand.prototype   
 *  - This notetag will work for windows belonging to proto or having  
 *  proto in its prototype chain   
 *  Both the Window_ and .prototype part doesn't need to be included
 *  in proto   
 *  For example: Status stands for Window_Status.prototype   
 *  proto only accepts prototypes starting with Window_   
 *  - The inputs corresponding to down and up selection commands will  
 *  be reversed if downUp is t   
 *  - The inputs corresponding to right and left selection commands   
 *  will be reversed if rightLeft is t   
 *  - The inputs corresponding to pagedown and pageup selection   
 *  commands will be reversed if pagedownPageup is t   
 *  - The inputs corresponding to ok and cancel selection commands will
 *  be reversed if okCancel is t   
 *  - Only the working notetag with the highest priority will be used

 *  # Actor/Class/Equip/State manipulations   
 *  1. meta.reverseInput   
 *  - Returns the reverse input flags in the form of {   
 *     proto: proto,   
 *  downUp: b,   
 *  rightLeft: b,   
 *  pagedownPageup: b,   
 *  okCancel: b   
 *  } with proto and b being the window prototype and booleans   
 *  2. meta.reverseInput = {   
 *     proto: proto,   
 *  downUp: b,   
 *  rightLeft: b,   
 *  pagedownPageup: b,   
 *  okCancel: b   
 *  }   
 *  - Sets the reverse input flags in the form of {   
 *     proto: proto,   
 *  downUp: b,   
 *  rightLeft: b,   
 *  pagedownPageup: b,   
 *  okCancel: b   
 *  } with proto and b being the window prototype and booleans   
 *  - All meta.reverseInput changes can be saved if
