file_column: patched for imagemagick and validation
Hi all, I patched file_column to add imagemagick transformations of uploaded content. I added an options hash, and it takes the :magick and :format keys. :magick is a string of imagemagick command line options for convert (Reference: http://www.imagemagick.org/script/convert.php).

How do I validate using associated objects?
This doesn''t make any sense to me anymore. I have an Upload that belongs_to a Comment. Within my Upload model I expect to be able to access the associated comment with comment.foo.
