Ruby on Rails

Not elegant, but I did manage to get Paperclip to stop deleting or
overwriting the previous versions' attachments (I am using
vestal_versions here for that part). The path I took was to patch
attachment.rb and storage.rb from Paperclip. In attachment, I look to
see if the instance was versioned, and if it was I would inject the
version number into the filename before Paperclip saved it. In the
same file, I patched the clear method to never delete an instance that
was versioned.

In storage.rb, I did the reverse, and let the flush_deletes method
remove a non-empty folder.

Both of these changes are fairly risky, in that they require the
parent model to have a version method, which I ended up having to
provide like this:

def version
false
end

in anything that had a file attachment but didn't have versions. I'm
pretty sure this could be improved on a lot.
