Make it possible to serve Barkeep from subpaths rather than just root

[thomasjenkins]

Unless I've somehow totally missed it, Barkeep seems designed to only work if served from "/". Nginx proxy and rewrite rules can nearly get you there but the paths generated by Barkeep are not relative so all links and POST URLs do not work.

Yes, you're right, everyone to date has hosted Barkeep on its own domain or port, e.g. barkeep.mycompany.org. There is a way to make Rack's mounting point configurable, but various bits of code and tests which assume "/" would need to be updated.

Hello, has there been progress on this? I have all my other code services running in subdirectories so it would be nice to be able to be consistent. Thanks!

Also my SSL cert only covers one specific subdomain, so it would be preferable to stay with that.
