Replace dependency on mutt in `narada-patch-send` with Email::Sender and
POWER::GPG (release it to CPAN first).

FIXME Test/add Innodb support (mysqldump tests which pass on MyISAM are
fails on Innodb).

Add non-interactive mode for narada-install to use in CI/CD.

Switch from bash to /bin/sh: https://wiki.ubuntu.com/DashAsBinSh
