Title: Specify stable branch for hub `--HEAD` installs

Master branch is becoming very unstable really soon and switching from Ruby to Go, so people that use `brew install hub --HEAD` will have a really rough time during that.

Until we submit a pull request updating hub formula to the Go version, it will be friendly to our users to lock them onto a stable branch that promises it will keep working as before.
