Add Extra Data to LiveDto

[HuckinB]

At the minute the current return of the LiveDto is
[
'is_live',
'streamer_name'
]

However I'm suggesting that you add further data to this. For Example,
[
'is_live',
'streamer_id'
'streamer_name'
'streamer_art'
]

This way it's easier to cross reference streamers by ID.
