[PATCH] emacs: Show cleaner addresses during message display.

[David Edmondson]

Remove double quotes and flatten "foo at bar.com <foo at bar.com>" to
"foo at bar.com". If the address is of the form "name <foo at bar.com>",
show only 'name' with a tooltip of the address.

More aggressive simplification and tooltips.
