ENH: default jobControl now under the '~/.OpenFOAM/jobControl' directory
- this implies that jobControl is a user-resource for OpenFOAM. It was previously located under $WM_PROJECT_INST_DIR/jobControl, but few users will have write access there. - an unset FOAM_JOB_DIR variable is treated as "~/.OpenFOAM/jobControl", which can partially reduce environment clutter. - provide argList::noJobInfo() to conveniently suppress job-info on an individual basis for short-running utilities (eg, foamListTimes) to avoid unneeded clutter.
