Commands assume git master branch

[adamlwgriffiths]

All git commands assume master branch. "git push #{extract_app_from_git_config || "heroku"} master"

Git branches are the best way to manage various deployment environments (staging, production). This is done by specifying the local branch to push from git push <remote> <branch>:master

Hardcoding this to master prevents the majority of users from using this tool for any git related commands.
