Options: Removed writerStandalone, made writerTemplate a Maybe.

Previously setting writerStandalone = True did nothing unless
a template was provided in writerTemplate.  Now a fragment
will be generated if writerTemplate is Nothing; otherwise,
the specified template will be used and standalone output
generated.  [API change]
