Bring back roomtags to normal channel fok r ia

[Bunny]

Training already has IA (= Infinite Ammo) enabled per default. So I guess you meant to ask for R to be an option for training?

(Team Training, CTF, Humans VS Infected, Turbo and Team Turbo also have IA enabled per default. Humans VS Infected also has R enabled per default, just so you know)

Since i believe we have a feature that prevents you from picking quest when some tags are enabled in the room, why not do the same for r and ia? Let players use them in every room, but if a player attempts to start a game while a tag is enabled that should not be allowed in that mode, like r in tdm, it would tell them they cant.
