Create twitter_favorite agent

Agent that returns favorite tweet of given user

Added history, number and clean up

'history' is buffer to hold historical tweet.id this can be used for memory optimization, 'number' is number of latest tweets that Agent retrieve.

+      The Twitter Favorites List Agent follows the favorites list of a specified Twitter user.
+      #{twitter_dependencies_missing if dependencies_missing?}
+      To be able to use this Agent you need to authenticate with Twitter in the [Services](/services) section first.
+      You must also provide the `username` of the Twitter user, `number` of latest tweets to monitor and `history' as number of tweets that will be held in memory.
+      Set `expected_update_period_in_days` to the maximum amount of time that you'd expect to pass between Events being created by this Agent.
+      Set `starting_at` to the date/time (eg. `Mon Jun 02 00:38:12 +0000 2014`) you want to start receiving tweets from (default: agent's `created_at`)
