Optimisation Goal

I have tested the change of optimisation goal in vGroup, CSG and Carl Stuart test drives and havent found anything unusual. It's hard to know exactly what the impact will be but the setting we have at the moment seems invalid - it isnt even listed as one of the options. So, I think we should change it, If necessary it can be changed back instantly. So, i think we should put it in the version scripts and do the usual of QA testing, in-house testing and then roll-out steadily.
