Call printchplenv from smokeTest script.
Deal with gcc/gnu...
Disable clang build for travis for now. It fails to compile.

See failed build output here:

Rename launchcmd-for-aprun-launcher -> chpl_launchcmd.py
Generalize pbs launchcmd such that a slurm class can be created.
The problem conveyed by this test was resolved when the deprecated method
file.open() was removed from the modules.  It will not be relevant again.
Generalize module docstring so it will apply to both slurm and pbs
Start on SlurmJob implementation of AbstractJob.

It only knows how to call squeue right now.
