Writing to dpm@Vienna

updated signal samples in samples_13TeV_CSA14.py and samples_13TeV_CSA14v2.py
fileprefix to ease local running (was asked for by Maria)
extension of pybatch.py and batchmanager.py in order to write to Tier2 in Vienna

closed #176 because it is redundant.

You should change also the name in the string passed as first argument of `makeMCComponentFromEOS` and not just the name of the object in python.  i.e. it must be `Xyz = kreator.makeSomething('Xyz', ...)`  and not  `Xyz = kreator.makeSomething('Abcd', ...)` 

Can you fix this in both files?

Sorry for taking this long to look at them
