metatag 7.x-1.6

This release includes a few important improvements:

• The entity selection logic added to v1.5 has been improved. All content types, vocabularies and the user entity will now automatically be enabled when the module is installed, while other entities are disabled; an update script is included that will enable meta tags for all content types, vocabularies and the user entity, other entity types are left as-is.
• An API improvement will automatically search values for image URLs that might happen to be embedded in formatted image links. This removes the need for other modules to get the URL for an image field, it can now be automatically extracted.
• The Open Graph Product meta tags were moved into a separate sub module, as were the Dublin Core Advanced meta tags.
• A few more meta tags were added, including Apple's new SVG favicon standard.
