Given a list of cultsRegistry, checks whether any component would respond to the given event and if so, executes the
event handler defined in the component.
function callHandlers(cults, e) {
    var broken = false;

    for (var i = 0; i < cults.length; i++) {
        var cult = cults[i];
        var handlers = cult && cult.events && cult.events[e.type];

        if (!handlers) continue;

        var selectors = Object.keys(handlers);

        if (callHandler(cult, e, handlers, selectors) === false) {
            broken = true;
            break;
        }
    }

    return broken;
}
