[Radiant] Featured Pages extension

[Jim Gay]

Announcing the featured pages extension

SVN repo at http://www.saturnflyer.com/svn/radiantP/featured_pages/

Alters the pages table to add a featured_page boolean column, adds a  
checkbox for the option on the page edit screen, and provides the  
<r:featured_pages> tag.
It requires that Shards be installed.

See the README for details http://www.saturnflyer.com/svn/radiantP/featured_pages/README
Or the 'Available Tags' documentation on the edit screen once installed.

Haven't written any tests (sorry, I'll be adding them).
