Title: only show the backstage button in top level windows

the backstage button doesn't really make sense in a confined space
such as an iframe.

TiddlyWiki's backstage experiments in http://backstage.tiddlyspace.com
raised this issue. It also allows you to do weird things such as have
a TiddlyWiki within a TiddlyWiki within a TiddlyWiki by continually clicking
the tiddlywiki link in the menu.. eek!
