Teamcolors when speccing FFA

[sprunk]

When speccing FFAs use the same teamcolor scheme as when playing, which results in 1 blue team and N-1 warm colors.

This makes the blue team look more salient than it really is while making the warm teams blend into each other. Perhaps speccing an FFA should use the whole gamut of colours? With shades of the main color for team FFA.

So a 3v3v3v3 would have a palette e.g. like this (note, still avoids the "self" green)
