metatag 7.x-1.0-alpha7

Changes since 7.x-1.0-alpha6:

• Added support for showing the token browser with a dialog when http://drupal.org/node/1684984 is fixed.
• Added a more generic and reusable metatag_page_set_metatags() and metatag_page_get_metatags() rather than having to add and inspect a static variable for each entity type.
• #1281770: Do not show the meta tag form or skip metatag_entity_view() if an entity does not have any custom meta tags or does not have any non-global defaults.
• #1706156: Fixed metatag_metatags_delete_multiple() did not actually delete anything due to an improper array_keys() on the array.
• #1448412: Added static cache for db_table_exists() in metatag_metatags_load_multiple().
• Added an option to metatag_config_load_with_defaults() to skip loading the global config.
• #1708718: Fixed output on node pages (stems from #1363476).
• Simplified conditions in _metatag_entity_is_page().
• Increase default weight of metatag fieldset.
• #1363476 by jenlampton: Use hook_entity_view() to add meta tags to the page.
• #1466292 by DamienMcKenna: Placeholder file for documenting the API.

Warning: meta tags won't load on taxonomy term pages due to a bug in Drupal core, follow http://drupal.org/node/1700160 for more details.
