Fix #243: Add optional location field to events

[cassidoo]

This lets a user add a location to an event and creates a chip for the location in the schedule.

The contributing guide is updated, and this also removes the "View More" button on the schedule because they aren't needed.

The diff looks larger than it really is, Copilot added location stuff to some of the events already listed, and did some formatting! Look at the components/ folder more than anything.
