Attached is the updated patch which includes all of the previous plus 
the following:
   * graph styling / layout improvements and fixes
   * performance improvements, a few of the graphs on the summary page 
are now being preloaded and returned w/ the request (js still used but 
not to call back to the server)
   * VM Pool Graphs, temporary solution using the hosts associated with 
with vms in pool to collect stats implemented

If everything looks good, essentially the only thing remaining with 
pre-summit graphing is to hook up the backend for the flexigrid load 
graphs (and more performance improvements if required)
