* disable web login annoyance in campaign/skirmish menus
* Send the move event to all players.

* We are using the step timing for hidden actors' step sounds, also if an actor
  appears in the middle of the move the reaction panel event timing breaks,
  as we rely on the timing of the step that caused the actor to appear.
* Fixes bug #5147 (Footstep sounds play at the same time)
* Might fix bug #5156 (Reaction fire panel persists)
* [AI] Don't ignore the line of fire test for fire modes after the first one.

* Extracted AI_CheckLineOfFire
* Fix hidden shot event timing.

* The EV_ACTOR_START_SHOT isn't sent for hidden actors, so we can't rely on
  shootTime for the first shot.
* Don't just perish the ET_ITEM arbitrarily in G_MissionThink.

* There might be other items at the floor there.
* Fixed manual loading of weapons in the equipment screen.
* quick workaround for the broken loadgame menu
