HaikuDepot: Introduce new PackageState' pending'

When installing a package, it is set to pending, which removes
the Install button from the package info area. When multiple
packages are downloaded, theould all be put to pending,
right now, they will still offer to be installed, although they
are already scheduled for downloading. Requesting a package to
be installed when it is already schduled will mess things up later.
Godm, I hate this nano bug...
