fixed the More link in the search sesults to properly pass the category&subcategory along.
added analytics account #
Created the basic framework for creating and displaying saved search alerts.
I'm thinking about turning the Saved Query section into a table, this commit is my backup in case that doesn't work.
Firstly, tables did not work.  Second, this is the completion of the saved searches portion of work, which has been designed with the idea of adding alerts to it.
added save alert button to tracker page.
added a button and property allowing for seaches to become alerts, and made a few minor changes to layout and searchresults.  I also added a new template page 'trader_search.html' to deal with the saved searches / alerts.  Maybe not exactly necessary, but I thought it would help clean up 'trader.html' somewhat.
Completed the section that runs text searches over the SavedQueries that are saved as Alerts when new posts are made.  I still have to set up the actual emailing functionality, but everything up to that point works - line 219 in bitlist.py is a logging.info line that indicates that emails were sent out, which is what I ahve been using to test the system up until now and it appears to function correctly.
Added email functionality to the spot indicated in the last commit and ironed out a few details in the implementation to make it all work.
minor changes made to layout after seeing the updated layout with the existing information from the appspot db.
