* (bug 2991) Add teamoverlay, an optional hud display showing names, health, class/equipment, and locations of teammates

  - Disable with cg_drawTeamOverlay 0 or remove it from your hud
  - Control number of teammates to show with cg_teamOverlayMaxPlayers
  - When teamoverlay is enabled, show health of teammates next to their name when the crosshair is over them
  - Servers who dislike gameplay effects or want to save on bandwidth use can use g_allowTeamOverlay 0 to disable the feature for players
  - Special thanks to Risujin for bring this idea and the original patch to Tremulous
* Cache teaminfo on the server and send only when needed (Undeference)
* Increase frequency of sending updated teaminfo (Undeference)
