Redmine

This seems to be requested often:

http://www.redmine.org/issues/4968
https://www.chiliproject.org/issues/166

Currently people are working around this limitation in various ways (adding attachments by mail, constructing multipart form requests, ...).

I just started learning rails and the redmine internals, but wouldn't it be possible to just pass the attachment as base64 encoded string inside the issue, -json / xml?

On the issue controller side, something like this might work (it did work for me while testing things out with curl):

Not pretty but kind of works. If someone could help me out a bit, I guess we could implement something much cleaner pretty quickly.

Bonus points if the thing works out of the box with active resource ;)
