Kit Manager: split available kits by dependency compatibility

Renamed "Kits to be installed" to "Kits available on the computer"
for kits whose dependencies are all in the app. Kits with unmet
dependencies go into a greyed-out "Other kits on the computer" section
that cannot be selected or ticked.
