StreamStatus

Implemented streamStatus function. The following values are not implemented yet and currently returns default values:

`playbackSpeed` - returns `1`
`isPlaybackSpeedChangeable` - returns `false`
`isSeekable` - returns `false`
If playing a stream with audio, then (without calling stop), calling play again with a stream with no audio, streamStatus will still report 'true' on audio. These bools needs to be reset on row ~123 aswell.
