Merge pull request #52 from julien040/fix/issue-46

Fix/issue 46 - Untracked files are shown in `gut status`

Changes made:
I've also changed the way files are added to the staging area. Now, depending on if git is installed, gut runs git add . or adds using go-git. Previously, due to a bad condition, both were done.
Finally, checking if the working tree is clean also ignores untracked files.
