[Users] update new user guide for non-TeraGrid/XSEDE users?

Cactus uses certain software packages (C compiler, Fortran compiler,
MPI, queuing system) which differ on basically every HPC system.
Instructions for building Cactus are therefore either targeted to a
specific system, or have to say "please read the system's
documentation to figure out these things". There is nothing in
particular that makes our instructions target TeraGrid systems; in
fact, we are targeting LONI systems, which are not part of XSEDE.

If you follow the instructions at
<https://docs.einsteintoolkit.org/et-docs/Tutorial_for_New_Users>,
then these should work almost as is on Hopper. The are two
differences:
1. You have to leave out the "soft add +git" since git is available by default.
2. Since Hopper has 24 cores per node, you need to use a multiple of
24 cores when submitting a job. Use "--procs=48" instead of
"--procs=32". You can also add "--num-threads=6" if you want to use
OpenMP as well (which should work out of the box).

At the UC-HIPACC school at LBL Erik showed us how to build/run on Hopper at NERSC (I'm a regular NERSC user so this was very helpfu), and the steps were considerably different. Unfortunately I didn't write down what we did and so am now a bit stuck. So Erik, if you're reading this, could you look through your shell history and maybe dig up the commands you used? :-P
