Menu Rendering Error on Items Containing Single-quotes

There is a parser error on the rendering browser (FireFox) because the single-quote is not a valid character in the generated menu identifiers. Solution is to include the single-quote as a "forbidden" character in the dynamically generated identifier.

Module: dhtml_menu.module
PHP Line: 253

Change From:

$forbid = array(' ', '(', ')', '{', '}', '[', ']');

Change To:

$forbid = array(' ', '(', ')', '{', '}', '[', ']', '\'');
