Allow multiple values for config settings

Browse source 
Setting a list as a value for `global-config' will instruct gitto to
place that setting in the config more than once. For example:

,----
| (set! global-config
|       '(("remote \"origin\""
|          ("url" . "git@somehost.com:~a.git")
|          ("pushurl" "git@somehost.com:~a.git"
|                     "git@someotherhost.com:user/~a.git"))))
`----

Will produce output similar to:

,----
| [remote "origin"]
|         url = git@somehost.com:repo-name.git
|         pushurl = git@somehost.com:repo-name.git
|         pushurl = git@someotherhost.com:user/repo-name.git
`----

The ordering may vary depending on what was already found in the
`origin' remote's settings.

gitto doesn't know or care which settings can and cannot appear more
than once in a configuration, it is up to the user to provide valid
values.
