View.triggers should include the DOM-Event

[okitu]

I'm working on a CompisiteView which displays a table, and the rows should be multi-selectable. The rows (ItemViews) have some triggers, which are catched, by the CompositeViews.itemEvents (#875 made this a lot smaller, thanks for this one!).

But here's my problem. I have no DOM-event in the handler anymore. Consider the example below:

var TableRow = Backbone.Marionette.ItemView.extend({
    triggers: {
        'click .select': 'click:select'
    }
});

var Table = Backbone.Marionette.CompositveView.extend({
    itemView: TableRow,

    itemEvents: {
        'click:select':'clickRowSelect'
    },

    clickRowSelect: function(eventName, args){
        // selection-code here
    }
});

Completely awesome what you can do in just a few lines of code.
Nevertheless, I have no DOM-event in clickRowSelect, so i can not check if the user uses ctrl, shift or alt to click on the rows, which i have to, to create a good selection ux.

By just adding the DOM-event to args i could do just that.
https://github.com/marionettejs/backbone.marionette/blob/master/src/marionette.view.js#L103

// build the args for the event
var args = {
    view: this,
    model: this.model,
    collection: this.collection,
    e: e
};

Of course, sometimes, there is no DOM-event, but then, also collectionis undefined most of the times.
I can't see a reason, why the event is omitted, but maybe there is one?
