Qualify Hunchentoot symbols and remove :use

[Zulu-Inuoe]

This makes the code more consistent in style and makes clear things like what function a method is specializing. Further, handle-request is now clearly the local function rather than the one from hunchentoot by the same name

Hey all, just a couple of changes while I was learning a bit more about clack and hunchentoot - The code seemed inconsistent about its :use because some symbols still had hunchentoot: and others did not.

I think in reading code (even as the maintainer) it is generally preferable to use prefixes/import-from.

If you'd like to see the code updated to not use prefixes, but to use :import-from on all the symbols, that's something I don't mind doing.

Thanks!
