Read Tile sampling Fractions from COOL
Incorporates !53384 (closed), !53387 (closed), !53388 (closed), !53389 (closed) from @ssnyder.
This version allows the Tile Sampling Fraction conditions to be read from COOL, but disables the G4Version comparisons for non-simulation jobs. This combined with Scott's previous fixes allows the previously affected unit tests and CITests to succeed still.
Leaving this one as a draft until I hear back from @harkusha.
