Enhancement: QC: Find outliers

[AMChalkie]

For QC I want to see if others would find this useful: I think it would be nice to see all genes where one replicate is a large distance from the others. So if you have values of 100,100,8000 for a given gene in a given condition it would be useful to highlight this. My reasoning is that if a sample has a a few of these it might point to problems in sample prep/sex matching.

I think you find these best with the MDS plot - and looking at the new "Gene" plot when hovering on genes.
