Allowed MPS section names to be used as names for columns, RHS, ranges, bounds etc by only accepting them as section names if nothing follows on the line.

Doesn't work for NAME, OBJSENSE, QCMATRIX and QSECTION, since they can be followed by text.

No sane modeller would use "RHS" as a column name, but I've found one that does!
