Thank you @eric-hu for reporting this regression.

Closes #583

Conflicts:
	README.md

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.

An implemenation of the watermark processor alluded to is in this gist
https://gist.github.com/1171081

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.

Conflicts:
	lib/paperclip/upfile.rb
	paperclip.gemspec

This will prevent someone to think that Paperclip test suite for master branch is currently failing, as the build was failed on a WIP branch, not the main branch.

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

This reverts commit cde22564.

Add rubinius to travis testing

Bump rails 3_1 version to rc6

This reverts commit fe01ae69.
