Summary: markupbase handling of HTML declarations

Initial Comment:
Using Python 2.2., I tried to use websucker.py on this 
page:

http://magix.fri.uni-lj.si/orange/start/

This resulted in an exception in ParserBase._scan_name 
because _declname_match failed.  Examining the source 
for the page above, I see there are several tags that 
look like: "<![endif]>" where the first character 
after "<!" is a '[', not an alpha as mandated by 
_delcname_match.  Perhaps this is badly formed HTML (I 
see it was produced by FrontPage), but if not, it 
appears that _scan_name may have to be modified.  FYI, 
here's the traceback from the exception:

Ugh!  I don't think that's legal HTML at all.  I'll have to
think about the right way to deal with it.
