* Reorganised the doc wiki's todo/* pages, using a link/tag to flag

* Allow pagetemplate plugins to override *anything* in the template.
* Add a meta plugin, which allows specifying various metadata about pages,
  like license and author. It also allows for inserting html link and meta
  tags into html, overriding the title, and adding hidden WikiLinks, which
  can be useful when using link-based globbing for page categorisation.
* Remove preprocessor directives from inlined pages.
* Allow simple preprocessor directive values to be specified w/o quotes.

+This plugin allows inserting arbitrary metadata into the source of a page.
+Enter the metadata as follows:
+
+	\\[[meta field="value"]]
+	\\[[meta field="value" param="value" param="value"]]
+
+The first form sets a given field to a given value, while the second form
+also specifies some additional sub-parameters.
+
+You can use any field names you like, but here are some predefined ones:
+
+* link
+
+  Specifies a link to another page. This is used to generate a html
+  <link> tag, and also as a way to make the wiki treat one page as
+  linking to another without displaying a user-visible link. The latter 
+  can be useful when using links to categorise pages. A html link tag
+  would look like this:
+
+	\\[[meta link="foo.css" rel="stylesheet" type="text/css"]]
+
+  A non-user-visible [[WikiLink]] would instead look like this:
+
+	\\[[meta link=otherpage]]
+
+* title
+
+  Overrides the title of the page, which is generally the same as the
+  page name.
+
+* license
+
+  Specifies a copyright license for the page, for example, "GPL".
+
+* author
+
+  Specifies the author of a page.
+
+If the field is not treated specially (as the link and title fields are),
+the metadata will be written to the generated html page as a <meta>
+header.
+
+This plugin is not enabled by default. If it is enabled, the title of this
+page will say it is.
+[[meta title="meta plugin (enabled)"]]
