Direct email sending support

[psss]

It would be nice to have an easy way to send/email the gathered report directly from command line, optionally with editing it:

• After report is generated the content is open in $EDITOR
• When the content is empty, no email is sent (as git commit)
• Otherwise an email is sent based on the user config

Command line examples:

status-report --edit .......... just edit & print on stdout
status-report --send .......... send directly
status-report --send --edit ... edit & then send

Config example:

[email]
subject = [Status Report] Week $week
from = Petr Šplíchal <[email protected]>
to = Some Manager <[email protected]>
cc = Petr Šplíchal <[email protected]>

That's it! :-)
