This commit adds the waterbottles from DayZ Mod. The icons were made by @DeVloek. The waterbottles are fully functional with all actions. To boil a plastic waterbottle you need an empty trash can.
Dogs could not be watered with other waterbottle than the ItemWaterbottle itself. This is fixed now. Also fix missing reset action from hide body.
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.
