* Send policy key of "0" when validating; this gets us the policies
even if "Allow..." is enabled (currently, we simply don't see the
policies)
* If we don't support all of the policies, send back the response
code indicating support for partial support. If we get a positive
response back, then we're good to go - the server allows devices
with partial support. Otherwise, we fail as we always have - with
the toast indicating that the device doesn't support required
policies
* Remove PolicySet.isSupported() and ensure proper field ranges
within the constructor
* Update tests as appropriate
