rtcds changed to run LIGO userapps-user-env.sh to set user environment variables.
If available, the script loads after /etc/advligorts/env
rtcds also now prefers USERAPPS_LIB_PATH, USERAPPS_MEDM_PATH, USERAPPS_SCRIPTS_PATH used in the site script when setting up RCG_LIB_PATH, CDS_MEDM_PATH, CDS_SCRIPTS_PATH.
