Only getting one cell per class when running [read_lib -S 80 -G 3]

[b62833]

@alanminko

In src/map/scl/sclLibUtil.c, should line 889 be

SC_LibForEachCell( p, pRepr, i )

instead of the current

SC_LibForEachCellClass( p, pRepr, i )

?

With the current code the GENLIB created only as one cell per class (e.g. only one buffer cell, even if many are available in the library).

For reference, making this change locally solves my problem. I don't understand abc enough to know if it breaks anything else.
