Fixing some generated pages:

1. `js/maps.js` wasn't escaping single quotes properly in venue names, so I stopped trying to be clever and just used escaped double quotes around things.
2. Updated the airport list to include new instructors.
3. Updated the flags in the team and previous bootcamps pages.
4. Moved some old bootcamps to the cache (while trying to debug the escaping problem).
