COLESLAW::URL unbound error

[jsjolen]

When I do (coleslaw::main "my/project/path") the above error is signalled.

It is signalled by the static-page plugin when it loads my only defined page and it fails in the following function code:

(defmethod initialize-instance :after ((object page) &key)
  (with-slots (coleslaw::url coleslaw::text format) object
    (setf coleslaw::url (make-pathname :defaults coleslaw::url) <- error here
          format (alexandria:make-keyword (string-upcase format))
          coleslaw::text (render-text coleslaw::text format))))

Since coleslaw::url is unbound the MAKE-PATHNAME call will fail.

This is a minimal .page file for reproducing the bug:

And this is my .coleslawrc

url: must be provided as a header to a static-page's file. Also all headers must be non-empty.

EDIT: I will be supplying a pull request that informs the user of what is required of them as a more sensible error soon.
