View git status in dashboard

Related to #2.

As a developer, I should be able to view the git status of my local repository in the dashboard

1. When selecting a file in “git status” (changed or untracked)

• Show option to show diff
• Show option to stage – then it goes to stage list
  1. When selecting a file in “git status” (staged)
• Show option to unstage file
• Show option to discard changes
  1. At any time when there are “staged” files
• Activate button to commit
  1. At any time when there are “no changes”
• Show button to pull
  1. Show “how many commits ahead of origin” and if ahead, then show button to PUSH
