Disconnect from the Citizens Script Repo

If this ever worked, it stopped working at least several months ago,
maybe a year.
Nobody really expected it work... I recall auf agreeing that it should
be deleted (a long time ago, before I had even committed to Denizen...
would've done it earlier but I forgot by the time I had started
committing)
If you want proof it's old, just look at the '/citizens denizen repo
load'...

(+ Downloading any random script with a matching name and running it,
without even being able to look over the script first, is now very
dangerous with the current power of Denizen)
