Regarding this change (and the underlying behavior).
I see the key word is "full set of packages". Which makes little sense in case
of upgrading from local archive. But it also makes very little sense, if
upgrading from internet.
What if it would only check packages when it is necessary? I.e.
1. Read installed packages list.
2. Compare to setup.ini, calculate upgrades.
3. Let user make their mind.
4. Calculate dependencies.
5. Download packages. (Skipped if installing from local directory.)
6. Calculate hashes. If any selected package fail the check (damaged or
missing), notify the user and put them back to the package selection screen.
7. If all hashes checked ok' - install packages.
