Fixing formatting (concept maps to bullet points)

Fixed formatting - "concept maps" should be in bullet points
If the name of a venue contains a single quote, such as "St. Mary's
University", the map on the bootcamp index page wasn't rendering
properly because the string containing it `js/maps.js` was in single
quotes.  We did have a `replace` in our template, but it wasn't
working.  This PR switches to a double-quoted string with explicit
escapes for the quotes around the `href` value - not 100% safe, but
good enough for everything we're doing.
