[PATCH] Relics game mode

[Lionkanzen]

Condition Collect the relics to start a countdown to win.

Collecting all of the available Relics on a map in a standard game will additionally initiate a timer that counts down to the victory of the player holding them, or their team if "Allied Victory" is checked during the pre-game. Relics captured by the player's allies will contribute to the team's victory so long as every single Relic on the map is in possession of a team member.

1) There must be something (a particle effect?) that makes sure a player can immediately recognize a relic as being one.

2) They must fit into our time window (evidently!)

3) They should fit with biotopes/civs on the map (iow multiple relics)

Don't really want to add more patches to the rfc queue right now, but this patch is a proof of concept for a "Relics" victory condition. In this patch individual players or teams must capture all relics, which are units (as opposed to "picking them up" which has been discussed but would require #28). One gaia-owned relic per player is spawned in neutral territory at the start. The relic template is a placeholder (it uses a packed seige actor).

Some points/issues (many of these in the thread):

• This game mode won't work on some "special" maps (i.e. Survival of the Fittest)
• On the random map "Northern Lights" with map size "Tiny" there is a chance that the relics can't spawn, but this is an edge case.
• Like wonder victory, there should be different timeout options
• The relic actor(s) could be given the "sparkle_goldmine" particle to make it stand out.
• Relics could be allowed (required?) to garrison.
• There could be a notification when a relic has been captured.
• Relics could be given territory decay to make things more interesting.
• When spawning the relics, the trigger script could try to distribute the relics evenly across the map instead of just purely random.

Capture The Relic gamemode with catafalque flavor was implemented in ​D152 / r19345. We should open separate ticket for the artifact + garrison mode (requiring #28) once we foresee to implement that.
