git-multimail: update to version 1.0.0
This commit contains the squashed changes from the upstream git-multimail repository since the last code drop. Highlights: * Fix encoding of non-ASCII email addresses in email headers. * Fix backwards-compatibility bugs for older Python 2.x versions. * Fix a backwards-compatibility bug for Git 1.7.1. * Add an option commitDiffOpts to customize logs for revisions. * Pass "-oi" to sendmail by default to prevent premature termination on a line containing only ".". * Stagger email "Date:" values in an attempt to help mail clients thread the emails in the right order. * If a mailing list setting is missing, just skip sending the corresponding email (with a warning) instead of failing. * Add a X-Git-Host header that can be used for email filtering. * Allow the sender's fully-qualified domain name to be configured. * Minor documentation improvements. * Add a CHANGES file.
