Google Analytics / Cleanup

The Google Analytics code was on the page twice.

The first snippet had a TrackingID that I didn't recognize so I created a new analytics site under the Code for America account with the tracking ID UA-20825280-10

The second snippet looks like it was the Google Analytics Tracking ID for the main cfa web site so I remove that one.  Also it looked like the Chartbeat code from the CfA website was inadvertently copied in there as well so I removed it.  

Removed the erroneous .DS_store files as well.

General white space cleanup.
