[Cdash] ITK appears in GDCM cdash

This was a good one. So we found a limitation of the crc32 algorithm. In 
that case the two tests: 'itkBinaryDilateImageFilterTest-100-150-1' and 
the missing 'TestDumper', even if they are different, are returning the 
same crc32 value. So CDash thought they were the same and assign the 
previously stored (itkBinaryDilateImageFilter) to GDCM instead of 

It is not surprising but I was hoping that we could avoid this type of 
collision even with a descent size database (currently storing 
12,417,508 tests on cdash.org).

One option is to use md5 or a more complex algorithm, but then we will 
need to do a string matching in SQL and I'd like to avoid this if we can 
for speed reasons.

I'm open to suggestions,
