Gridviewer improvements

We were able to complete a few substantial improvements to the Gridviewer application. The changes listed below were deployed on the training node (http://ncphi.phgrid.net:8080/gridviewer/):

1. Added download csv extract functionality per query request. (Click on Download Data to get an extract)
   
2. Added HTML data table display with sortable columns per individual query request as well as a combined data set . This feature is currently needing improvements in speed. Further improvements could contain subtotaling by regions or dates. ( Click on Display data link to see control. )
   
3. Corrected bug in the console log with the time displays.
4. Appended build version on the title and header.
