 * @plugindesc v1.01 Replicates the effect of the Godspeed Rune from Suikoden

 * -----------------------------------------------------------------------------
 * ABOUT THIS PLUGIN
 * -----------------------------------------------------------------------------
 * The Godspeed Rune in Suikoden is a special rune that has two effects.
 *  1. When the bearer of the rune is in your battle party, you can dash faster!
 *  2. When the bearer of the rune is in your battle party, escape never fails!
 *
 * This plugin will recreate those effects for your chosen actor.
 *
 * 1. When the chosen actor is in the battle party and all conditions set in the
 *    parameters returns a true result, escape is guaranteed. Otherwise, the
 *    normal escape process chance will occur.
 *
 * 2. When the chosen actor is in the battle party, your dash speed is doubled!
 *    Walking speed is NOT affected!
 *
 * This plugin overwrites the default escape chance processing and the default
 * setting for movement speed outside of battle. Any other plugins that may
 * also alter these default functions may make this plugin incompatible with
 * your project, so please test accordingly.
 *
 * Overwritten: BattleManager.processEscape [rpg_managers.js]
 * Overwritten: Game_CharacterBase.prototype.distancePerFrame [rpg_objects.js]
