commit 8da6a2a adds production cuts for protons

[Laurie Nevay]

Resovle issue #66. Geant4 does not intend you to set individual range cuts for earch hadron. To ensure accuracy, they say it's best to only adjust basic primary particles like gamma, e+- and proton and indeed only provide easy methods for these (range setting doesn't appear to work for other unusual hadrons in the same way). Replace prodCutHadrons with prodCutProtons and the user should use the defaultRangeCut for all the other types.
