templatekw: use a list of tags in getlatesttags() instead of joining them
This will be used in the next patch.
It also points out that the documentation for '{latesttag}' is not quite
accurate, since it says "most recent global tag" (singular). I assume it is too
radical of a change to convert it to a list of strings. At least ':' is
currently a reserved character in tag names.
