Major freezetag rewrite. Implemented it as a "freeze" mutator that's usable with most teamgames. The Freeze Tag gametype always uses the freeze mutator, but has a different cvar prefix.

Capturing a flag in Freeze CTF will unfreeze all players
Faster melt by default in freeze
Added g_domination_spawnpoints_min and g_domination_always_available
Merge branch 'unstable' into freeze
Added unfreeze waves to the freeze mutator
Always reset global warming while the game is not in progress
Default g_freeze_global_warming_minratio reduced to 0.4
CTF and Keyhunt key/flag caps now reset global warming
Players that die 3 times in a row will get relocated to a random spawm point in Freeze
Small domination and spectating tweaks
"takes" field for domination/total domination by default
removed 100-armor-on-revival (wasn't intended)
Remove the TeleportPlayer_NextFrame entity after teleport (fixes a leak)
Jailbreak: imprison at death frame, but actually teleport in next frame. Likely fixes the rare false double frag bug.
Fixed a bug that caused new players joining during a Freeze game to spawn outside of the map
Merge remote-tracking branch 'origin/freeze' into freeze
Merge branch 'unstable' into freeze
