* feat(presence): display status in thumbnail and large video
- Create a React Component for displaying presence. It currently
connects to the store for participant updates but in the future
should not be as smart once more reactification occurs.
- Modify filmstrip css so the presence status displays horizontal
center and below the avatar.
- Modify videolayout css so the presence status displays horizontal
centered and with a rounded background.
- Dispatch presence updates so the participant state can be update.
- Update message position on large video update to ensure message
positioning is correct.
* squash: do not show presence message if connection message is displayed
