metatag 7.x-1.5

This release includes a huge number of improvements. The primary changes are:

• All entities (that are not configuration entities and have view modes) can have meta tags added to them, it's no longer necessary to change anything in hook_entity_info().
• The settings page (admin/config/search/metatags/settings) provides full control over which entities may have meta tags added to them.
• It's now possible to change the theme region used to trigger meta tag output, which will allow sites to work around problems with meta tags not being output.
• Using tokens to replicate one meta tag into another works correctly now.
• An import program is provided for sites upgrading from Nodewords and Drupal 6.
• Almost 250 meta tags are now supported, including App Links, 29 more Dublin Core tags, Open Graph product tags, mobile tags, favicon tags, etc.

There are two change notices for this release:

• API change for how Metatag identifies compatible entities
• Change in how Metatag loads entity info
