Rocket Arena 3 multi-map support

[Irbyz]

Rocket Arena 3 was a Clan Arena/Elimination mod for Quake 3.
The latest version can be downloaded here: https://www.mirrorservice.org/sites/quakeunity.com/modifications/rocketarena3/ra3180.zip
It includes the official RA3 maps. There are many custom ones as well, e.g.:

RA3 maps are multi-maps, i.e. each map consists of several arenas inside the main map, in which players can play simultaneously on the same server. In RA3 the arenas could be accessed through the menu or through a hub arena with teleports to all others.
I'm not sure but I think the available weapons and amount of ammo could be also set per arena.
Apart from original RA3 mod, at least CPMA mod https://playmorepromode.com/ also supports RA3 maps.

The RA3 maps we currently use are "ported", i.e. either one arena is cut out of the original multi-map, or spawn points are removed on all arenas except one.

Maybe it can be also useful to have an option to force one single arena while disabling all others, then it could be added to the map list and callvoted with either custom alias or some naming scheme automatically assigned to arenas, e.g. ra3map12-2. It could be also used to place all players into particular arena without disabling all others.
