Support server-side routes to non /api paths

[dazwin]

If I implement a route as follows...

   app.get('/permalink/:slug', function(req, res, next) { next(); });

it causes the browser to simply throw a 404.

Per @BrockMcKean, special handling has been implement on /api to avoid #! in URLs

I'd like to be able to implement non /api routes server-side, preferably with no additional code other than implement the express route per above.

This may also be the reason that Swagger (at /docs) currently does not work
