digium_git: Add additional capabilities for manipulating branches/tags

This patch adds the following:

* The ability to specify which branch should be tracked when checking out and
  creating a remote branch. This is needed anytime we don't want to track
  master in the newly created remote branch.

* The ability to checkout a local branch or tag. When a remote branch already
  exists, we don't want to create it again.

* The ability to check if a remote branch exists. This prevents errors,
  and lets scripts pick whether they want to create a remote branch or a
  local branch.

* The ability to commit local changes, and push them to the 'origin'
  remote. This includes both tags and branches.
