Groups: Added userservice/create_project call. You can now create a project in 
the database if you have CAP_MANAGEPROJECTS.
Also tried to standardise dates. ISO 8601 seems to be the best option (short of  
using the unix time which is pretty unreadable).
The 'deadline' parameter expects a ISO 8601 like string (at the moment 
something in the same form as what json.js does when called to parse a Date 
instance ie.  `(new Date()).toJSON()`). Really we should be far more flexible 
than that, but Python surprsingly doesn't have a good way to deal with ISO 
dates. We might have to write our own parser - see common.util.parse_iso8601() 
for an absolute minimal implementation.
