Turn format function into a generic method

Browse source 
This changes the way formatting functions can be customized in the init
file to:

,----
| (define-method (print (repo <repository>))
|   (format #t "~a: ~d up; ~d down; ~a. Updated ~a~%"
|           (repo-name repo) (repo-pushable repo) (repo-pullable repo)
|           (if (repo-clean? repo) "clean" "dirty") (repo-updated repo)))
`----

Note that it is possible that REPO doesn't exist, so you should always
check for that first.
