MenuOnClose Event?

[HannibalZA]

Would be nice to have an eventHandler to catch when the menu closes.

This helps with some cleanups and more global post-action procedures.

Currently the only option would be to put repetitive code under each action.

Something like so...

        onClose: function($elem) {

            alertify.notify("Done with : " + $elem.text());

        },

By adding:

   /* user-defined function to execute parting methods against opened element...*/

    onClose: _.noop,

And further down
// close the context menu

BootstrapMenu.prototype.close = function() {

    // hide the menu

    if (this.$openTarget) { this.options.onClose(this.$openTarget) };

    this.$menu.hide();

    clearCloseEventListeners(this);

};

This is rough, but I've added it for my own purposes.

That's a good idea, I'm happy to accept a PR if you want to give it a try. Otherwise, I'll take a look at it during the following days
