dayz_zombieSpeak and player_alertZombies are called often together or should be. fnc_alertZombies groups them together and uses the given parameters. This streamlines and corrects the missing or incorrect calls from dayz_zombieSpeak or player_alertZombies.
There is no point in having two variables for the same purpose.
It is also pointless to keep an action count tally like r_action_count
was doing, since it is only ever checked for being 0 or 1. Any count
higher or lower than that is irrelevant.
I will make this change in vanilla too.
Related to #1567, so I made this a function so it can be reused. People
should call this whenever they are adding a toolbelt item which the
player may already have. It has localized strings and handles spawning
the weapon holder on water, land and rooftop.
Tested both the sledgehammer and key copying. Confirmed all three
conditions are working.
