Plotting issue with TimeSeries experiments

[nishaann]

In findSim.py, under parseAndRun function, a call to 'advanceSimulation' under simWrapMoose.py is made but it is not handling the doPlot argument. This is happening in simWrapHillTau.py and therefore TimeSeries experiments works well with HillTau models but its not happening with detailed model.

Line 754-755:
if ( qe.t > currt ):
sw.advanceSimulation( qe.t - currt, doPlot = getPlots )
