Check the server if a package can be updated

The server is queried using the local packages_id and version to
determine if they can be updated. The Manage button state is set
accordingly. This is done in an async way to keep the UI responsive

A.t.m I'm not sure if I might need to move this logic out, since
we also need to make this query when check periodically for updates.
when the list is not shown. But that would also entail creating
the installed packages list before the Manage Packages tab is ever
created in the Marketplace.
