Page Index Implemented

ALSO:

* implemented "blessed pages"
I.e. functionality for marking a page as special enough to warrant a
link of its own in the sidebar

* implementation of "blessed pages" is also a technology demonstrator
This shows us how I want the revamped licensing system to work later
Defining three macros (head, body, footer) which takes the posts selected
license as parameter, and outputs different html tags for the different
macros.

M_LICENSE_HEAD should output META tag
M_LICENSE_BODY should output <a><img/></a>
and the same goes for M_LICENSE_FOOTER

Unsure if we need two macros for that, kindof depends if we want the
footer to point to our licensing page, or to the same target as *_BODY

* general cleanup of blah_draft

* general cleanup of blah_publish

* add pages.idx template

* moved posts.idx into setup/templates
