Add a go1 branch

[kylelemons]

I recommend adding a go1 branch for the go tool to check out (e.g. not a tag). As long as no changes are made to that branch, it's pretty straightforward to push changes over to it when you're ready for them to be "released"

set -e git tag $RELEASENAME git push --tags git checkout go1 git merge master git push --all git checkout master
