Awards bugfix

While doing the content updates to the Awards, I noticed the recent build of that book is broken.

http://www.star-fleet.com/library/bookshelf/awards/index.html

Note that 2007, 2006, and Charter all point to "awards-charter.html", and all have the same content (the 2007 awards ceremony). This is because the article-ids in charter.xml, january2007.xml, and july2006.xml were all "awards-charter".

So I fixed that. All three files now have unique article-ids.
