Added to NmssmSoftsusy rewsbMu, rewsbM3sq, rewsbXiS, rewsbSvev, rewsbKap, rewsbmSsq, rewsbmH1sq, rewsbmH2sq routines for imposing EWSB on individualo parameters, rewsbTreeLevel to impose tree level EWSB, doTadpoles to call tadpole routines and set them, iterateMu, iterateSvev and rewsb to do ewsb at one loop level.   These have been tested bewtween Lewis and peter versions and with various sanity checks and against flexi susy where popssible.  The one loop parts in particular may still have bugs in some cases and/or stabilty issues, further testing is needed.  Alternative ewsb routines should be added later too.
