There was an issue on assignment another S3 attachment object to another object whereas calling #to_file on S3 attachment will create a Tempfile, which would then having a different file name than original version.

By caching the filename first before calling #to_file, we're ensuring that filename is the original one.

Fixes #9

Thank you @Bonias for reporting in

Closes #590

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

Closes #569, Closes #603

Thank you @excid3 for suggestion.

Closes #582

However, this will make sure that you can always change it to something else afterward.

There's currently no test for this, but after I've tried this with the `integration_test` branch, I can confirm that logs are written to `log/test.log` as it should.

Closes #581

Thank you @eric-hu for reporting this regression.

Closes #583

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

When testing if post_processing is set, the method should be used. This allows plugins to overwrite the post_processing decision. This is useful for plugins that want to do the post_processing in a background processor.

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

Abstract out the file geometry parser within Thumbnail. This makes it possible to have different cropping and scaling controls, as the papermill gem does.

I think it's OK to have the bugfix for MongoDB in the plugin.

This reverts commit cde22564.

This reverts commit fe01ae69.
