Patch which fixes this bug.

Since SBS 7.4 was released,
Slim::Networking::SqueezeNetwork::Players::disconnect_player() hasn't worked
with any of the SqueezePlay based hardware: SBTouches, SBRadios, SBControllers.
 The effect of this has been to break the 'disconnect aa:bb:cc:dd:ee:ff
www.mysqueezebox.com' interface as well as the SBS webUI's abiltiy to fetch
back SP-based hardware players.

If Line 348 in Players.pm:

$http->get( $http->url( '/api/v1/players/disconnect/' . $id . '/' . $ip ) );

..is replaced with:

$http->post( $http->url('/jsonrpc.js'), 'Content-Type' => 'application/json',
to_json({
        id     => 1,
        method => 'slim.request',
        params => [ $id, ['connect', $ip] ]
    }) );

..so that the disconnect request to mysb.com is made via jsonrpc, this fixes
both the CLI problem and the webUI problem.

I've successfully tested this fix with the following hardware:

SBClassic
SBBoom
SBReceiver
Transporter
SBController
SBTouch
SBRadio

It would be nice if this fix could be back-ported to 7.5.4 too.
