[Cuis-dev] Reload button in package list tool

[Luciano Notarfrancesco]

Yes, perhaps it could show an error if the package defines methods in base
clases or classes of other packages, otherwise it could lead to
inconsistencies.

Also, if the newer version on disk has fewer methods/classes than the
installed version, or if some classes have been renamed, does it work as
expected? I never tried it, I got used to starting from a fresh image.
