Projectserv: single line registration syntax for simple registrations

[Fuchs]

As discussed: it would be nice if there was a single-line syntax for easy project registrations, something like

/msg projectserv register projectname #channelspace cloakspace contact1 contact2 contact3

chances are that space is not a good delimiter because for projectname it is potentially valid (didn't check the code), feel free to take whatever is sane.

A single-line syntax for projects with multiple channel / cloak spaces is debateable, but I'd say the above will cover 90% of cases and make people very happy.
