Nice to have: Embedded map on event details page

[benjaoming]

Just a cherry on the birthday cake.. but if we can render all the events on a big map, maybe we can have a zoomed-in map on the event detail pages? (see the events/single.html template)

Edit: Wanted to note that:

• this will also be part of an effort to make all events have an intermediate detail page on the site itself, rather than immediately exiting the site when clicking something.

• the map might have all the other events visible, too! Zoomed and centered on the current event, and with its marker highlighted.. but the other events visible, too.
