OCR scanner and image validator SA-plugin

Checks for specific keywords in gif/jpg/png attachments, using gocr. This can be used to detect spam that puts all the real contect in an attached image, accompanied with random text and html (no URL's, etc). There are also various rules to validate attached images and detect forged content types or broken images. This plugin needs SpamAssassin 3.1.1 or later. The version 2.0 is able to defeat recent gif animations which use gif tricks to avoid OCR.
