0002441: "friendly-stealth-invisible" flag doesn't work
Changeset
Backport: Trunk 8299 + 8302; the proper way to fix Mantis 0002441 is by modifying the team_visibility_update function && follow-up to 8299: we need to check visibility for our own team in case we have a friendly-stealth-invisible ship covered by AWACS, or something\nalso, clarify terminology: in-frustum/not-in-frustum replaces visible/invisible\nand do some minor rewrites for additional clarification
