There should be a way to add metadata to a page. Probably a plugin could do
this, for example:

	\\[[meta foo="bar"]]

Uses for this include:

* Setting a page title that's not tied to the filename.
* Any metadata that's generally useful on html pages.
* Maybe as an alternate way to tag a page, like linking to the tag,
  except it doesn't have to show up in the page text.
* Recording page licenses.

[[meta link=done]]
[[meta title="supporting metadata..."]]
[[meta author="Joey Hess"]]
[[meta link="foo.css" rel="stylesheet" type="text/css"]]
