 * @plugindesc Use basic escape codes in any window for any text
 * @author Modern Algebra (rmrk.net)
 * @help This plugin allows you to use basic escape codes in any text field, so long
 * as you include \* in the text field. By default, the options are limited to
 * \c[n]; \i[n]; \v[x]; \n[x]; \pn[x]; \{; \}; and \G. They may be expanded by
 * other message scripts which add escape codes, but not likely by all such
 * escape codes as some would be necessarily restricted to the message window.
 *
 * When using codes like \c[n] and others that change the font settings,
 * remember that you should set it back to normal afterwards. In other words,
 * write "\*\c[3]Text\c[0]" and not just "\*\c[3]Text"
