Usage:  $me go

Helps your edit/deploy/test loop when testing directly on a "tyamz"
dev heroku instance (as opposed to testing locally).  Meant to be
called from your $sb branch, it automates these steps:

  - switch to deploy_keys branch
  - merge latest changes from $sb into deploy_keys
  - push deploy_keys to heroku "tyamz" instance
  - switch back to $sb branch, ready for subsequent edits

To deploy to production, manually do steps something like this:

    git checkout -q deploy_keys
    cp warts/yamz/.seaice* .
    git commit -a -m "key swap"	# IMPORTANT! so production keys are pushed
    				# test keys: logout of yamz, then back in
    git merge -q -m "lots of bug fixes" master
    git push -q heroku_production deploy_keys:master
    cp warts/tyamz/.seaice* .
    git commit -a -m "re-swap"	# IMPORTANT! revert to test keys in future
    git checkout -q master
    chmod 600 .seaice*
