Merge branch 'release/0.172' into develop
fixed setting of max_user for queues
when using bash Job now detects pipe failures... are there any commands adversly affected by this??
improved determine_queue() algorithm to make better queue choices - not does weightings instead of always picking the queue with the most hosts first
added -lpthread to LIBS so that this compiles on newer machines when RTLD_NOW is passed to dlopen
updated tests to work with more recent VEP, though now we have problems when vcf has no records...
version bump
