 * ResourceModification jobs (/modify + /anonymize) can now use multiple threads to speed up processing

+* Introduced a new Housekeeper thread in Orthanc (different from the Housekeeper sample plugin).  This thread
+  regularly try to give back memory that Orthanc no longer uses to the system.  This reduces the overall memory
+  consumption.  However, only the memory at the end of a memory arena is given back to the system.  Fragmented memory
+  is not given back and therefore, the memory consumption may still stay high.  More information in 
+  OrthancServer/Resources/ImplementationNotes/memory_consumption.txt.
