Changed the default path listed in the comments of the Storage module. The default path now listed matches the default path from attachment.rd line 9

slight refactoring in geometry.rb to - only calculate transformation ratio if image needs to be cropped (Clemens Kofler)

Removed extra filename parsing in metadata cleaner. If it hadn't been done yet, your files won't be renamed anyway.

Added paperclip:refresh:metadata and :thumbnails tasks, and a paperclip:refresh task to tie them together. Also, paperclip:clean checks validity of the attachment, not the whole model instance.

Calling #valid? on the model corrctly runs validations on the attachment. Calling #valid? on the attachment correctly runs validations instead of reporting only on current status.

No tests yet since I had problems getting the suite to run :/
