Paperclip::InterpolatedString will ensure that we're not double escape the string, which was the cause of the escaped filename problem in #path method.

Saving instances causes memory leaks in development mode in rails.

It's Paperclip's responsibility to escape special characters from the URL to make sure that it's comply with standard.

Closes #577, Closes #563, and reverse my judgement on #482.

It was working fine for me locally

fixes #588 . Attempt to log warning message when 2 models use same attachment name with default url interpolation

This will make sure Interpolations is comply with Ruby's Object#hash

Closes #569, Closes #603

Thank you @excid3 for suggestion.

Closes #582

Fixing destroy callback to delete files just when model destroy method was completed successfully (i.e. no exception like 'foreign key constraint violations' was raised)

Adding tests and logic to ensure that tempfiles are closed and unlinked after queued_for_writes finishes uploading/saving

Decouple the Interpolations class from the Attachment classs, you can extend Paperclip with custom interpolations as paperclip-extended does.
