The name attribute of requirements is used when generating options for the :optional and :recommended dependency tags. Unless otherwise specified, the name attribute of a Requirement will be populated by stripping any module prefixes from the beginning and "Dependency" or "Requirement" from end of the class name and downcasing the result. Closes Homebrew/homebrew#17759.
