Fix scaling of vector bosons in VEVandEpsilon.py

Now matches the definition of Ellis et at in 1303.3879.
This is also consistent with ATLAS-CONF-2014-010.

[MCMC] Dynamic burn-in has no effect

MCMCCalculator calls SetConfidenceLevel on MCMCInterval when creating it.
SetConfidenceLevel calls DetermineInterval, which compute the interval from the Markov Chain
for a given confidence level. This results is cached, so if we change the number of burn-in steps
after, it'll have no effect.
