Update HMS version to 2.2.
Fetch the rules when master server cvar set. Print rules
in console when server register. Display the rules in the
menu when entering the server hosting menu or when
changing the advertise cvar.
Removes rooms, replaced with cv_advertise and "Advertise" on the host menu.
According to the new API, SRB2APPLICATION is sent instead of MODID. A contact
field was added, but there is no means of accessing it or setting it.
As a slight change, the server list will be populated even on an outdated
version of the game. (The new API was designed with this in mind.) The update
alert is still presented first of course.
The new default is 15 minutes as well. And if you think that's too long, I have
confirmed that the Master Server delists inactive servers after a whopping 40
minutes, at least.
