Fix HDF5/JPEG install problems with newer lib versions on Windows

I added the -ppn (process per node) option to the JobSubmitter_mpiexec and JobSumbitter_qsub class.
Now both the mpiexec and mpirun have the -ppn option.

I had a problem with the -osmesa flag not working on RedHat. The engine would still load the system 
libGL.so.1 library. This was happening because the -osmesa flag added the osmesa path to the end
of the LD_LIBRARY_PATH. I moved the osmesa path to the front of the list and everything works great.
I don't see any problem here. Only the libraries in that directory are our links to the osmesa library
and you are adding the -osmesa flag to make sure that they are loaded.

fixed piping error

I went to add a no config option to the visit-install script and found
that one already existed. It is invoked using "-c none".  While looking 
at the code I found that there were several configurations that were not 
implemented with the "-c" option, so I added the missing ones. I also 
added a "-test" option that tests all 21 configurations. I also updated
the help text since that was out of date. I added a blurb about the
fix to the release notes. This resolves #1282.

I corrected a couple of bugs in the ADIOS reader where 3d uniform and
rectilinear meshes where read incorrectly. I added a blurb about the
fix to the release notes. This resolves #1753.

I corrected a bug with a previous fix of mine to the OnionPeel operator
to properly handle the case where the seed cell was specified as a global
cell number and material interface reconstruction was applied. I updated
the release notes with a description of the change. This resolves #1772.
