[Zope] kludge: 2.4/HTMLDocument

I wanted to install Evan's new ZPT, so I made a fresh Zope 2.4 installation from scratch. I noticed there's something I forgot to put in my install script... HTMLDocument/HTMLDocument.py needs to have __implements__ = IHTMLDocument # XXX ??? commented out. I forget exactly why I did this the first time. This time I noticed that the HTMLDocument icon was broken. This fixed it. --kyler
