1) I modified the internallauncher so that parallel jobs launch properly on
   Sandia's redsky and redsky-s systems.

2) I modified the host profiles for glory and redsky to use hdf5 1.8.4
   instead of 1.8.7. When I used 1.8.7, there was a mismatch between the
   headers from 1.8.4 and the library from 1.8.7, causing the hdf5 based
   readers to fail. I assume that the 1.8.4 headers were coming from a
   system location and switching to 1.8.4 for visit solved the problem.

3) I changed all the sandia host profiles to use ssh tunneling to get
   around their firewalls.

4) I modified the visit-install-open script to turn on logging when
   installing on glory and redsky.
