Issue 142: FTMemberMarkers fix JIP issues

[shadow-fa]

Previously this component was drawing white markers for JIP players.
This was because fn_LocalFTMarkerSync was only "syncing" the values if they had changed from the group leaders perspective.
Additionally it would only sync if the group leader did not disconnect.

I'm not sure if this is the best solution to the problem, but I'm open to discuss any alternatives.

See also issue #142.

Can't this component be significantly simplified now that assignTeam is global and with #163?

Quite a lot of the logic in this component (and what caused the JIP issue) is the syncing of the team colours using a variable on each unit, all of which is now redundant. So that logic could be removed and the markers just drawn based on the (now global) assignedTeam.

[shadow-fa]

It already is simplified because the syncing is gone.
What still has to be done is storing the colour in a variable for each unit, because at some points in the game (e.g. when the unit is controlling a UAV), we can't get the colour from the command assignedTeam because it would return nil. This would lead to the problem, that some units would sometimes have a different colour.

[SamLex]

Yeah, I should look more carefully before commenting.

Also, doesn't this run (unnecessarily) on the server (no hasInterface check)?

[shadow-fa]

It should run for every unit that has an interface, including the server if it isn't a dedicated server.

[SamLex]

Yes, but doesn't it currently run even on machines without an interface?

You're right, I got it confused with another PR.
This (see last commit) is what you meant, right?
