f717ce56b0b340dab4738809cae485c739456293, ref #34
Revert "Force all users to non-beta tester, ref #47"

This reverts commit 66ac974fbe97e89f34814df9c8d981154252038e.
Update MixItUp, fixes #41
Allow custom listening port and move nconf

Nconf was moved higher up in the process for this to work properly. All
nconf calls are standardized to `nconf` rather than `this.nconf` in some
places. Fixes #48

Developers: please update your local environment variables (env.json or
actual environment) to include any missing keys, specifically
`"httpServerPort": 3000`
Fix Facebook iframe size, fixes #50
Remove legacy versus route, fixes #42

As the poll IDs changed in #43, the old routes will not exist so it is
safe to remove.
Version bump v0.2.7
