Add delete option to episode's context menu

This PR makes following changes:

 - Adds delete option to episode's context menus in queue and feed list

 - Adds a storage preference that allows episodes to be automatically removed from queue when they are deleted (by clicking delete in context menu,
or pressing trash can icon on `Completed` tab of `Downloads` page)

 - Adds a test for the aforementioned preference
