cufon 6.x-1.0-beta1

Imported cufon.module from my personal Mercurial repository (http://hg.invisibleinstitute.com/drupal/cufon/).

Known issues:

• Font files should be cached to avoid filesystem calls on each request.
• Fonts should be available on a per-path (or some other system of selection basis) -- currently, all font definitions are loaded on every page request, realistically limiting the number of fonts you'll want to use to one or two.
