* Track memory leaks in allocations via the standard libraries, and

   avoid malloc/delete mismatches, by overriding standard new operator.
 * Added another global enable flag to memleak finder, which is used to 
   mark the end of static allocations and the start of dynamic code, 
   since the memory leak detection is done before cleanup of static 
   objects.
 * Added a public guard class, to allow safe scoped disabling of memory 
   leak detection.
 * Added InternalAllocGuard to protect against recursive loops when 
   allocating memory inside the memory leak checker. (refs #3)
