send keen public pageviews to partitioned collections

 * Log the public pageview events into collection buckets partitioned
   by the first letter of the project guid.  After one month, we will
   switch the analytics page to pull from the partitioned buckets.
   Since each bucket will have approximately 1/31 (there are 31
   possible letters or numbers that can appear in a guid) of the
   events in the common collection, it should make the analytics page
   more responsive.
