A larger bunch of smaller changes for unblinding of MSSM

- removed KS from ratio plots until better understood.
- adjusted min of postfit plots for x-axis range up to 1.5TeV in MSSM.
- improved robustness of x-axis range re-allocation for goodness-of-fit.
- added automatic finding of min and max for 1D-limit plots in MSSM.
- adjusted legend position in mA-tanb plots.
- adjustments on doMSSM for em specific control plots.
