Adding self's picture in chat controller too

[RajChanchal]

Hi Logan,
can we not add self's picture? I couldn't find any option in the code. There was property for opponent's image though.

That's currently not supported. A lot of the chat implementations I looked at while designing didn't use a picture for the current user and I think there's the assumption that the right side of the chat is "self".

If you'd like to add support for that and submit a pull request, please feel free to do so.

Best,

Logan
