Version 0.3: add autossh support
Added autossh support. mrgrctrnl will default to using autossh if it's
installed; otherwise it'll do ssh in a while loop.
I did include 'ExitOnForwardFailure=yes' in my ~/.ssh/config, but I'm
thinking I should include that in __SSH_OPTIONS to be more robust. Might
be in 0.3.1 or whatever.
Another thing in 0.3.1 should be man pages and stuff. Maybe that'll be
0.4. I like version bumps.
CHANGES HERE (right, that's what this message is for):
- add autossh support: -S forces ssh ; -A forces autossh
- rewrite usage; add config file example
- change config file syntax (backward-compatible)
- add a few other commandline options
