Several improvements: * Add possibility to work with multiple partitions (in web receiver). See ADAMATLAS-266 for more information. * Fix json formatting problems for histograms (pie charts) * When fill EoV and object-updated info, add low and high bound information close to query time interval. This solves issue ADAMATLAS-302 * Leave only one data point with timestamp smaller than "since" query interval and only one data point with timestamp greater than "until" query interval. This is another solution of first part of ADAMATLAS-300 issue implemented on client side.
