* Changed calling convention for httmllink slightly. The first three

  parameters remain the same, but additional options are now passed in using
  named parameters.
* Change plugin interface version to 1.02 to reflect this change.
* Add a new anchor option to htmllink. Thanks Ben for the idea.
* Support anchors in wikilinks.
* Add a "more" plugin based on one contributed by Ben to allow implementing
  those dreaded "Read more" links in blogs.
