Make it possible to use woo instead of hunchentoot

[naryl]

First of all, thanks for the awesome library!

We have a small web service using a web framework running on woo and it should be possible to use it for both the frontend and the rest service in the same system. I can take a look myself and if it's too much of a hassle I'll close the issue and we'll just run them in different systems.

Ok. I think the way to go would be to use Clack. I tried some time ago, but stopped in the end: https://github.com/mmontone/cl-rest-server/tree/clack.

Note that is very old stuff. Probably should be ignored, and start from scratch.
