grahamc/hydra2 - Change MMUBEIGVTTY7OESMGVEOL7EC7HNTSGFIIOC5C3UHKVFYHJ75EMVAC

hydra-queue-runner: Tweaked the selection method

Pick the jobset that has used the smallest fraction of its share, rather than the jobset furthest below its share in absolute terms. This gives jobsets with a small share a quicker start (but they will also run out of their share quicker).
