class DrupalSchemaMetaTag in Metatag 7

Schema meta tag controller.

This extends DrupalTextMetaTag as we need to alter variables in template_preprocess_html() rather output a normal meta tag.

This controller is little different from DrupalTitleMetaTag and same value in the itemtype instead of title. So in the MYTHEME_preprocess_html(), $variable['itemtype'] will be provided.
