Side channel in the PvP composition isn't re-enabled

[freghar]

This is because it's disabled by an Arma Additions CBA feature and the Execute Code then doesn't re-enable it, it only tries to disable others.

Change its code to

/* Chat channels for PvP - make sure Side is enabled */

addMissionEventHandler ["PreloadFinished", {
    0 = [] spawn {
        /* make doubly sure this runs after CBA settings */
        sleep 1;
        1 enableChannel true;
    };
}];

to actually re-enable the Side channel. Set Environment to Unscheduled otherwise it might not work.

Note that (to make this reliable for JIP, if we ever run PvP with JIP) the channel is re-enabled 1 second after entering the game, so any planning has to be done after the briefing screen.
