obslog: make changeset available to templater
obslog templating currently has very limited support for templating
the precursor changeset (when available). The only available keywords
are {node}, {rev}, and {shortdescription}. This patch makes the entire
changeset available to the templater by passing it to
formatter.context(). That function has been available since Mercurial
4.2.
