stage v0.1.1

Added

• u on a branch opens an upstream menu. The menu sets or removes the tracking
  branch.
• P names the remote that it pushes to. It offers a force push only when a
  force push can succeed.
• You can turn force push off in the settings. Both offers obey this setting.
• A branch row shows the check results of its pull request.
• / narrows the keyboard reference. It matches key names as well as labels.

Changed

• The review comment list reads like the diff. It quotes every anchored line in
  the colors of the diff, and the comment sits under the code.
• A long comment wraps. The list no longer cuts it short.
• A comment marks the lines that it describes. The range is visible on the code,
  not only in the header of the card.
• A comment card spans the pane. It no longer docks to one side of a split view.
• The staged and unstaged sections of a diff state which they are, in color.
• A created or deleted file fills the pane. It no longer uses half of the pane.
• stage update and the installer read one published manifest. An install and an
  update check cannot disagree about the current release.
• The installer is at stagetui.com/install.sh. The github.com URL serves the
  same file.

Fixed

• d on a file discards the staged changes too. Before this release, it reported
  success and changed nothing.
• A multi-line comment keeps the whole range lit while you write it.
• stage no longer assumes the cause when git fails in a repository with no
  commits.
