Bug #3278: SeqIO tries to use Gapped without import

@to_alignment@ in @SeqIO@ uses @Gapped@ (@ isinstance(alphabet, Gapped)@) but does not actually import @Gapped at . Thus a @NameError@ results. Although the method is labelled obsolete, it is used by @SeqIO@ in write when an @AlignIO@ writer must be used (e.g. when trying to write sequences to a Nexus file).

Solution: @from Bio.Alphabet import Gapped@
