Seamlessly integrates the spectator system with the vanilla respawn framework when the onDeath setting is enabled. This commit makes a lot of changes:
- Edit BI functions used by the vanilla respawn framework to enable support for ace_spectator.
- Set spectator state is now tracked using a GVAR for the local player since using a unit won't be reliable all of the time. However unit is still marked for any filtering purposes.
- Instead of NV being used based on the sun to moon transition state by default, that functionality only takes place in the integrated system so that custom frameworks can do what they want.
- Seagull units are hidden when using framework integration since they're spawned by the engine with respawn type 1 and they just hang around undesirably
Existing variable "ace_spectator_isSpectator" split into counterparts "ace_spectator_isSet" and "ace_spectator_isStaged" in order to better manage spectator events
-Localized keybinds.
-Removed fnc_cameraIntro.sqf; superfluous.
-Various code clean ups.
-Changed: Condition for mission end now checks allUnits (todo: change to allPlayers when available).
