The infrastructure to support a coherent participant experience at IEEE VIS, including watching, engaging with speakers, and socializing.

Changelog

Fixed the behavior that allowed user-driven seeking within the video when clicking multiple times. It was due to a measure meant to prevent continuous seeking for super low bandwidth. Testing found that this only occurs for bandwidths of less than 0.5 mbit/s for low quality streaming, so this is probably acceptable. Turned off this check to disable seeking.
Added support for multiple simultaneous streams by adding a URL search query, i.e. ?session=session1. Different sessions can have separate titles, videos, discord channels, and slidos.
Added support for window resize, i.e. resizing the window will cause the layout to refresh and adapt.
Added support for different stream states: WATCHING, QA, and SOCIALIZING.
- WATCHING has a large YouTube player and uses the Chat tab.
- QA has a large YouTube player and uses the Q&A tab.
- SOCIALIZING has a small YouTube player, a large Gather.town, and uses the Discord tab.
We now display the video name to the Video header on the page.
