 * @plugindesc Version 1.0 Allows skills to bypass skill costs that are greater
 * than their current amounts (MP or TP)
 * @author Maliki79
 * @help
 * After installing this plugin, tag skills with <bypassCost>
 *
 * When selecting skills, any MP/TP cost will be ignored.
 * Skills will still consume the needed amount, but if the actor
 * doesn't have enough, their points will be only reduced to 0.
