Added i18n support to models through globalize3.

* Added Post translation
* Added Category translation
* Use friendly_id globalize with category
* Added migrate_data option on migrations for translations
* Use Refinery locale instead of I18n
* Refactored duplicate locale_picker partial
* Removed useless .all call
* Use presence instead if / blank?
* Added with_globalize scopes when loading posts of one category
* Use Globalize when creating post factory
* Fix failing specs by creating blog posts/categories using needed locale.
