bitbake: hob: implement the "retrieve image dialog" + changes to image combo box

Tha changes related to the image combo box are related to the
action done in the retrieveImageDialog. When the user wants to select
a customize image, but then he cancels the action, the combo box is set to
--select a base image--.
If the user selects an image using the new dialog, a new item with its name
is added to the combo box list and then it is activated.
