templatekw: expose color name in {namespaces} entries
Templates make use of a "log.<namespace>" label. The <namespace> value
here differs from the actual namespace name in that the namespace
itself is plural but the label/color value is singular.
Expose the color name to the templating layer so log.* labels
can be emitted for {namespaces}.
As part of this, we refactored the logic to eliminate a gnarly
comprehension. We store color names in their own dict because the
lookup can occur in tight loops and we shouldn't have to go to
repo.names[ns] multiple times for every changeset.
