Disabling new user registration

[gmag11]

Is there any way to disable registration page? In private environments it may be useful for first user but then I prefer use email invite and disallow new user registrations.

#480

It looks like this was added as a feature request about a month ago. It would be incredibly helpful to have this feature for public installs.
