HaikuDepot: featured tab enable

When the application updates data, the
featured tab remains grayed out because
it is not being invalidated. This will
ensure it is redrawn as the state
changes.

Also the tab will be enabled as soon as
a prominent packaged is seen rather than
wait for the end of the bulk load
process.
