Barrages: guns fire only when manned (friendly soldier within 15 m, health > 0.5) and resume when manned again; fixed IFA_Barragers cleared before BuildInit (st_<gun> undefined - supply/alive/crew checks never worked), save.sqf barrager supply line (select [3]) and SEDCS parsing of it (RPT doubled quotes). Switch Roles dialog refreshes its lists every SEOWswitchrefresh s (openswitch.sqf v0.3)
