Changes:
small fixes to AliSelector, AliSelectorRL, CorrectionMatrix
AlidNdEtaAnalysisMCSelector uses Stack instead of TreeK directly
AlidNdEtaCorrectionSelector, AlidNdEtaSystematicsSelector now PROOF ready
PWG0base, PWG0dep only load the libraries that are not already loaded
new PWG0Helper.C that contains functions to send a PROOF query, is used by makeCorrection2.C, makeSystematics.C, runMultiplicitySelector.C, testAnalysis2.C
