Rake Tasks for the Translate Plugin

We’ve added two Rake tasks to the Translate plugin. The lost_in_translation rake task helps find I18n keys in lookups in your code that are missing from your default locale YAML file (i.e. config/locales/sv.yml in our case). The merge_keys Rake task is used in conjunction with Sven Fuchs’s Rails I18n Textmate bundle to move extracted keys and texts into their config/locales YAML file. Those two rake tasks have been quite helpful in our I18n work here at Newsdesk so we figured that we should share them with the community.
