#14 configuration file use

[Fred L. Drake, Jr.]

syncmail has grown many command line options, and is
likely to grow more as functionality improves. Some
potential functionality (such as per-branch
configuration) is expected to be fairly difficult via
the command line.

Using a configuration file would make it much easier to
configure syncmail.

It is most likely that an .ini style configuration file
will be used since a (somewhat) suitable parser already
exists in the Python standard library.

And, umm, while we are wishing..

1) Support for cvs tag expansion from loginfo.
2) The assumption that localhost will be used to connect
when no explicit MAILHOST is passed in blast_mail didn't
hold. I had to force this or I got connect errors. So, improve
robustness.
3) No diff option - nice but not always necessary.
4) Improve formatting of email subject from raw material
5) Make/restore a test mode for command line testing. That
was hard to do.
6) Allow user to set email debug level on command line.
