[Cosmo-dev] Magic URL's

[Morgen Sagen]

Supporting one URL for both Chandler and Cosmo UI is easy:  Chandler  
doesn't do a GET on the URL, so GET can be reserved for serving up  
HTML.  The difficulty is in dealing with icalendar file consumers  
like iCal and Google -- I don't think those clients support parsing  
HTML to find icalendar URLs, and so we'll have to have a separate  
icalendar-specific URL to support those clients.
