Fix a segfault; replace _typeRenderer with _scopeRenderer
Fix a segfault; replace _typeRenderer with _scopeRenderer

When _typeRenderer or a recently introduced _literalQuote are not
specified in the config file, GTAD won't crash anymore. Also, to
simplify configuration, _typeRenderer is replaced with much simpler
_scopeRenderer that doesn't include the type name and doesn't include
the always necessary {{#scope}}{{/scope}} bracketing.
