Enable the images from new dialog to be selected on double click or with Enter key

I think it would be a nice usability improvement that in 'Select image' dialog, 'Gallery' tab to be able to choose an image and to advance to 'Edit image' dialog by double clicking on the chosen image or by pressing Enter key.

In addition, it would also be nice to be able to advance to 'Edit image' dialog from other tabs: 'Document Tree', 'Upload', 'Icon', 'Url' by pressing Enter key.
