Need a close option
G'day,

Loving your project and I am finding it very useful. 

However I have one small problem. I'm using bootbox (a boostrap based dialog utility) to display a dialog to ask the user to select some information. Within the dialog I'm using your project, bootstrap-iconpicker.

However if the user selects to close the dialog (via the close button) without closing the iconpicker, then the iconpicker remains.

If there was a way that I could destroy the popup manually then I could destory any popups when the dialog close option is triggered.

Cheers,
James.
