 * @plugindesc Allows ☆ tiles to use the "Passage (4 dir)" setting in the tilesets tab of the database.

 *
 * V1.0 - 8.13.2015
 *
 * This plugin allows the user to define passage settings on ☆ passability
 * tiles, similar to how normal O passability is defined.  This plugin works on
 * its own without any need for settings.  It overwrites a single function but
 * should not interfere with any other plugins.  Nonetheless it should be placed
 * high in the plugin list.
