Allow images to be associated with questions

[GoogleCodeExporter]

Currently the only way to have images and other binary media appear in a
question is to reference it with an img html tag, which also requires that
the user have access to a public location to host the image. Ultimately
requiring quiz authors to contribute questions in html form is not
desirable since it is not secure or user friendly. There should be a means
to upload an image and attach it to a question. 

Only small images should be allowed, otherwise we could start bumping up
against the storage quota eventually.

Links to images (and audio files) can now be associated with questions. Decided
against allowing users to upload and store binary image/audio data in the 
quizlink
database, out of concern for bumping up against the storage quota.
