If the git repo is clean, the "Uncommitted Changes" line in the CommitList should say something like "Working tree clean" similar to how git says nothing to commit, working tree clean.

It would also be nice if the Item / text color changed. E.g. green for a clean repo, and bold red for a repo with uncommitted changes. Ideally the colors come from the existing palette / QPalette.

Also if the working tree is clean, then the user should not be able to select that line in the CommitList.
