Double click inside text field

[JeanBilheux]

would it be possible to double click a folder to enter this one, instead of clicking at the bottom of the panel the "Enter Folder". I noticed a few users who all add the same reflex of double clicking to try to enter the folder.

The current implementation uses ipywidgets.Select(Multiple), which does not support double-click event as far as I know. So to support this we need to implement a custom widget. Maybe we can extend the standard Select widget for this.
