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

• 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.
