Notifiers: XBMC update

* Added GUI/Config option to update only the first host in xbmc host list. This should appease everyone now.
* Added SB logo to notifications sent via the JSON-RPC (xbmc12)
* Fallback to testing the legacy http-api before just giving up on the host:ip -- should fix those running xbmc on xbox/non offical builds
* Fix the json update_library routine on updating shows with `,` in the path
* Cleaned up configNotifications.js to make jsLint/Hint happy as well as update code for jquery 1.9x as `.complete` is depreciated in favor of `.done` for the $.get calls.
* Fix merge conflicts that the NMJv2 pull created -- and cleaned up misc things with it in the GUI
