Log Message:
Don't use global menu_dir for calls to menu() with path starting with '.'

For scripts that set the global menu_dir (e.g. via JS bbs.menu_dir), let's
not require that all the files moved from text to text/menu (for example).

Problem reported by Amessyroom when using his custom shell and bullseye.js.
