[MV] Change Max TP value plugin release

/*:
 *
 * @plugindesc This is the simpliest way to change max TP value for actor
 * @author Landazar
 *
 * @param TP Base Value
 * @desc Base value of TP (default 25) you can put any other value
 * Negative values are forbidden!
 * @default 25
 * default: 25
 *
 * @param ID of parameter variable
 * @desc Variable is included to alter max TP
 * Negative values are forbidden!
 * @default 1
 * default: 1
 *
 * @param Multiplicator value
 * @desc Use this to multiply final TP result
 * Negative values are forbidden!
 * @default 2
 * default: 2
 *
 * @param Reductor value
 * @desc Use this to lower TP if you think you get to high value
 * Negative values are forbidden! Allowed values: from 1 to 10
 * @default 4
 * default: 4
 * @help This plugin can alter maxTP value of your actor to any desired value.
 * To alter max TP value by game progression you must define a variable
 * wich will alter TP, then in parameters put it ID to get formula working
 * e.g your var you want use is: '#0005: MaxTPalter', so in parameter you type 5
 * rest numbers is you desire, however
 * I wouldn't recommend huge numbers ( > 10000 )
 * view how to use it --> https://youtu.be/lnxO33zt3bA
 *
 * WARNING! Any attempt to use negative values will result
 * automaticly converting them to positive values!
 *
 * WARNING!! Any attempt to use strings in plugin parameters
 * will result setting default parameters inside funtion's code!
