templatekw: introduce the changessincelatesttag keyword

Archive is putting a value with the same name in the metadata file, to count all
of the changes not covered by the latest tag, instead of just along the longest
path.  It seems that this would be useful to have on the command line as well.
It might be nice for the name to start with 'latesttag' so that it is grouped
with the other tag keywords, but I can't think of a better name.

The initial version of this counted a clean wdir() and '.' as the same value,
and a dirty wdir() as the same value after it is committed.  Yuya objected on
the grounds of consistency [1].  Since revsets can be used to conditionally
select a dirty wdir() or '.' when clean, I can build the version string I need
and will defer to him on this.
