Templated main HTML (header, content, footer).

Still need to template the search/filter forms and the list of
latest apps.
Templated entire filter bar, including reset, keywords, license and categories.

Each of these is a different template, allowing them to be placed on
the page as separate blocks of content.
Almost finished templating all HTML.

Still have the error screen to template.

Also the XML of the atom feed could be templated, however I feel that
is less important because it isn't themeable and has to adhere to a strict
schema.
