[Feature] Add actual site and event info to root index.html

[BenG-SFDC]

just a feature request to set the index page for root to point to a site and/or event information page, links to common information like wifi passwords, etc.

Pie in the sky ask: add an in-page discord chat, tailored to a single channel for the event.

alternate PITS ask: irc channel maybe instead? just a place where its easy to chat on-site for folks who come in who may not have discord already
