This reverts all the last changes to server_playerSync and creates a new global variable for dayz_onBack. This should be the best way to save the gear correct and still get dayz_onBack if the player leaves the server. This change removes the constant sending of the whole player inventory over the network from force or regluar_save. It should no longer be needed since the server does the counting now.
Using "Wait for the previous action to complete to perform another" is
more accurate in these cases, because dayz_actionInProgress could have
been set by any action, not necessarily the same one.
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.
