Enable the 'Player.Label' property to be used in an Item. Without this change, the XBMC host (Gotham 13.1) will return an error, as XBMC does currently not support querying the 'Label' property. It does, however return this property with every other query by default.
XBMC - Add binding option to use 'Player.open' RPC call.

Use this in combination with a String item and a sendCommand call in your rules. The string should be set to the URL that XBMC needs to open.
