* Patch from Enrico that

- allows preprocessor directives to have parameters with no specified
    value
  - fixes preprocessor directive parameter parsing so that
    foo=bar baz now means "foo=bar" and a "baz" with no value
  - Add a tag plugin that allows more easily tagging pages.
    The meta plugin can also still be used for this.
