Add support for Sendmail
Here we go for the fix of #628 (closed).
email.transport is empty by default, which means Kresus won't send emails. User has to manually set it to either
sendmail to use
smtp for the previous behavior.
sendmail is used, emails are enabled and no further configuration is required. User can still set
sendmailBin to overload the path to
sendmail binary (might be useful to use
msmtp or things like this). If
smtp, the same configuration as before is expected.
