(Specials Parser)Allow Tag Field

Idea

Allow a tags field on specials

Gain

Provide easy reference to a group of specials in the locations field. In particular I'd like to be able to reference a group of specials in monster_fleets.inf as this would allow the guards placed in scripting to be automatically placed by the normal monster placement function during universe generation.

reference a group of specials in monster_fleets.inf

Could you write an example script you want to write and explain what it should do?

Sure. Something along the lines of:

MonsterFleet
    name = "SM_GUARD_1"
    ships = [
        "SM_GUARD_1"
    ]
    spawnrate = 6
    spawnlimit = 9999
    location = And [
        Not Contains Monster
        HasTag name = Guard_1
        Not WithinStarlaneJumps jumps = max(2, (NamedIntegerLookup name = "MIN_MONSTER_DISTANCE")) condition = Contains And [
            Planet
            OwnedBy affiliation = AnyEmpire
        ]
    ]

with the eligible specials having the tag Guard_1. Currently you have to list every special like this:
https://github.com/freeorion/freeorion/blob/master/default/scripting/monster_fleets.inf#L193-L197

What it would do, is the same as this:
https://github.com/freeorion/freeorion/blob/master/default/scripting/specials/planet/monster_guard.macros#L15-L26

except it would occur during universe_generation, be logged during universe_generation and be affected by galaxy monster frequency settings.
