New structure VmaStatistics, VmaDetailedStatistics, VmaTotalStatistics. Modified structure VmaBudget. New function vmaCalculateStatistics, vmaGetPoolStatistics, vmaCalculatePoolStatistics, vmaGetVirtualBlockStatistics, vmaCalculateVirtualBlockStatistics. vmaGetHeapBudgets function unchanged. Updated and rebuilt the docs.
