Removed the cache_dir, cache_filename_fields and cache_filename_format properties of IKOptions. While these were very powerful, I felt that it was unnecessarily confusing to have two properties (cache_dir and cache_filename_format) that determine the filename. The new cache_to property is modeled after ImageField's upload_to and behaves almost identically (the only exception being that a callable value receives different arguments). In addition, I felt that the interpolation of model properties provided by cache_filename_fields, though useful, would be better handled by a utility function outside of this library.
