color: enable branches support
This commit updates the branches command to use ui.label for the branch names
and the changeset. This implementation allows assigning colors to the four
states of a branch: active, closed, current and inactive. While you can
configure color for the four states, only current and closed have default colors
of green and black bold respectively.
