show: add basic labels to work template

`hg show work` is much more usable if output is colored. This patch
implements coloring via label() in a very hacky way.

In a default Mercurial install, you'll see yellow node labels for all
phases. Branches and bookmarks use the same formatting as the commit
message. So this change doesn't help much in a default install. But if
you have a custom colors defined for these things, output is much more
readable.

The implementation obviously needs some work. But for a minor change
on a feature that isn't convered by BC, this seems like a clear win
for the feature in 4.2.

# TODO there are a few deficiencies in this file:
# * Due to the way the file is loaded, references to other entities in the
#   template doesn't work. That requires us to inline.
# * The "namespace" of the labels needs to be worked out. We currently
#   piggyback on existing values so color works.
# * Obsolescence isn't considered for node labels. See _cset_labels in
#   map-cmdline.default.
