display status in default template

[davidB]

1. add info in the template to be able to track status and use it (as condition of display) (TBD)
2. update the default template (TDB)

• Uncomitted changes if there are unstaged or uncommitted changes on the checked out branch.
• Untracked files if there are untracked files which are not ignored.
• Needs push (BRANCH) if the branch is tracking a (remote) branch which is behind.
• Needs upstream (BRANCH) if a branch does not have a local or remote upstream branch configured. Changes in the branch may otherwise never be pushed or merged.
• Needs pull (BRANCH) if the branch is tracking a (remote) branch which is ahead. This requires that the local git repo already knows about the remote changes (i.e. you've done a fetch). Multi-git-status does NOT contact the remote.
• X stashes if there are stashes.
