PyPlot breaking parallel computing

@everywhere using PyPlot with julia -p 4 returns

Maybe try:

import PyPlot  # this already imports it everywhere
@everywhere using PyPlot

in case you are running into JuliaLang/julia#12381

Also, it's not going to work if you don't have Python installed in the same path on all the nodes.

I updated PyCall and PyPlot to master and can't reproduce. Thanks anyhow.
