Pairwise Fst plots - Only plotting one information on each plot

[jonbrenas]

Currently, pairwise Fst plots give the option to have the standard error (or the Z score) in the upper-right half. The problem is that with only one colorbar, it ends up with one of the two statistics being uniform in colour which looks bad. It is also much easier to read a whole row (or column) than having to turn halfway through. The idea is thus to have several plots instead of just one with one statistic in each.
