Last minute changes before 4.4

Here are a few bugs I have fixed and wanted to get in before the final release of 4.4.

1)There was a typo in the Param Input that was causing parameter 2 to not be sent to the method. 
2) Upgraded the Videostream Viewer in the screens app to work with the new remaining system available in the IPCam plugin.
3) I have also included my latest changes to the Sony plugin.
