Subject: [PATCH] config: Add 'config list' command

Add a command to list all configuration items with their associated
values.

One use is as follows: a MUA may prefer to store data in a central
notmuch configuration file so that the data is accessible across
different machines, e.g. an addressbook.  The list command helps
to implement features such as tab completion on the keys.
