pbs_mom: added two new config variables: 'job_oom_score_adjust' and 'mom_oom_immunize'. Both settings are linux-specific. First one sets /proc/<pid>/oom_adj for every mom task according to configuration. Second one prevents pbs_mom from being incidentally killed by oom killer.
* fix for mom_oom_immunize and job_oom_score_adjust: don't set limit's unless necessary
