Bug fixes in addNeutLoopGauge and addNeutLoopHiggs in softsusy.cpp.  In the contributions to the self-energy matrices sigmaL, sigmaR, and sigmaS, the sum over k ran from 1->4 (which is wrong because mch(k) is rank 2).  New if statements included (as in Ben's master code).  Empty diffs produced after running softpoint.x
