File upload example no longer exists

The book says that there's a file upload example in the Scalatra codebase's examples section, but there doesn't seem to be one anymore. It'd be good to get one in (I think I've got an example servlet kicking around, using Apache commons fileupload).

@mnylen it might also be good to get an example of the new file handling support you put into 2.1.x recently?

Yeah, good point. I started working on it now.

Cool, I'm doing up a Commons one right now as well.
