BUG: the hash was not actually checked for single input filters

Due to Lua expand template convolution, to compare the hash was
conditional on having an inputB. This was removed, but the displayed
text is reduced.
removed need for global hasher with hash compare macro
Moved NormalizeAndSave to be a member function
moved VERIFYHASH macro to IMAGECOMPAREWITHHASH

Moved this testing macro to be amongst the other image comparison
methods. Also added the output to CDash via a DartMeasurementFile.
Update hash for VotingBinary test

There was a bug in the ITK filter which didn't handle the pixel which
were neither foreground nor background. This hash is for the corrected
