Support 16 pilots + 1 cameraship in multiplayer

MW4Shell.cpp:
- CTCL_DefaultHostSetup (non-coop): replaced hardcoded
  Environment.NetworkMaxPlayers=16 with
  params->m_maxPlayers + (CTCL_GetTeslaCountAll() - CTCL_GetTeslaCount())
  so DirectPlay reserves one extra slot per installed cameraship.
  CTCL_GetTeslaCountAll() - CTCL_GetTeslaCount() = camera-only seat count.
- SetNetworkMissionParamater / PLAYER_LIMIT_PARAMETER: applied the same
  camera-slot formula when the host changes the player limit at runtime.
  Also restored the gos_NetServerCommands(gos_Commend_UpdateMaxPlayers)
  call (was accidentally dropped) and the missing break that caused
  fall-through into JOIN_IN_PROGRESS_PARAMETER.
- COOP branch: no change (capped at 9+bots; camera seats not needed there).

ConLobby.script:
- Raised the launch-guard cap from nTempPlayerCount > 16 to > 17,
  allowing the 17th connection (the cameraship) to not trigger the
  'Too many player/bots' error.
