tg mail: new command for mailing patches

Petr, since you've asked for help on this, here you are:

    $ tg mail [NAME]

a simple script to send one patch over email.

All it does is

    - call `tg patch` for actual patch preparation
    - extract email addresses from whom and where to send a mail
    - boils down to `git send-email`

It is self-hosted -- this mail was send by me with

    $ tg mail t/tg-mail

P.S. I'm not a bash guy, please do not beat me too much...
