bitbake: hob: create save image dialog used to save a template

Implemented a new dialog used by Hob. This dialog was desinged
in order to permit to save only in a particular directory.
Also, it has a field where the user can type a description
for the image.
Implemented in the handler a method to retrieve the topdir variable,
because the changes will be saved in {topdir}/recipes/images directory.
