Adding a new variable to entity_state_t?

?

ssqc?

entity_state_t is for server->client entities, and ents on the client. its fields are never readable from ssqc.
adding a team field is useless.

if you're using csqc then use the playerkey builtin to read a player's bottomcolor/topcolor setting (note: QW mods should use "team" instead). If your ent is not a player, you can use the colormap field to match it to a player, assuming you're using the non-dp-compatible engine deltaing extension - the regular csqc protocol which dp does actually support totally bypasses entity_state_t.

thus for both csqc and ssqc, it is useless to add a team field to entity_state_t.
