[PATCH v2] emacs: Add customization group for replying

[Michal Sojka <sojkam1@fel.cvut.cz>]

When one wants to customize the format of reply message, there is nothing
to tell the user how to do it.  Without knowing that construction of
reply buffer is actually implemented in the message package, it seems
that replying cannot be customized.

Because I was getting annoyed by the empty line the between the citation
line and the quoted message, I figured out that changing this is fairly
easy when one knows what to customize.

This patch adds notmuch-reply customization group that contains
references to the relevant customization options. The new group is easy
to find as it is shown as a result of running "M-x customize-group RET
notmuch RET".
