[MOAB-dev] MOAB distcheck failed.

[Jason Kraftcheck]

Apologies for the noise on moab-dev.  "make distcheck" is working fine.
This message was a test to verify that the nightly test script is working
correctly.

Updates to nightly testing:
 - Fix valgrind error suppressions for 32-bit HDF5 library.  Corrects
   bogus claims that nightly test for x86 is failing.
 - Better 'From:' address for nightly test messages
 - Set "Reply-To:" to moab-dev for nightly test messages
 - Remove noise in logs from valgrind: use '--quiet' to print only errors
