//ruleset validation:
//internal rulesets are taken at their word.
// we cannot verify the client build itself.
// its too easy to spoof replies from the client (eg by using a proxy) so there's not much point trying to sign things by hashing the engine binary etc
// and private keys in gpl software is not feasable.
//custom/external rulesets may get out of sync with the engine. or the file hand-edited, or poorly updated etc.
// we DO hash the rules and report them with the hash. this stops trivial text-editing cheaters.
// we sort the rules etc so comments or reordering does not affect anything, allowing for some maintainence of the files without functional changes.
// this ensures newcomers to a tournament do not have to worry about inadvertantly using a cheat, they just need to update their ruleset files (presumably alongside the rest of whatever mod(s) they're playing with).

changing a cvar to something and then back MUST still warn, in case its a cvar that locks down a command before being switched back.
we used to latch cvars so they couldn't be changed after querying, but this results in potential race conditions with other reasons to latch cvars. changing a ruleset cvar is now equivelent to just changing ruleset midgame.
