AnalysisTop: nominal weight name fix

Fixing a problem where whitespaces were removed from the names of weight variations where the name has a whitespace in the middle, e.g. " dyn= 3 muR=0.10000E+01 muF=0.10000E+01 “

Also, adding this new name to the list of common names.

Marking as urgent as it causes crashes if a sample has one of these unique names.
