Title: Default url with interpolation

Default url returned when there is no attachment, was using the defaut_url mentioned in the options, but was not supporting interpolation. As Paperclip supports interpolation for all urls including default_url, I have added support for interpolation in default url in this gem which wasn't working earlier.
