class comment should be updated. something similar to:

// Redirects Flash Download URL navigations, since Chrome already ships with
Flash.

Use your imagination :)

Also do you think it should be named similarly to the AppUrlRedirector? i.e.
FlashDownloadUrlRedirector?

I'm not sure, but think about it.

Changed the comment. ptal.

I decided to name the class FlashDownloadInterception because I believe that
what we're doing here isn't exactly a redirection. Is it? Correct me if I'm
wrong.

Maybe the name can be interpreted by some as an actual Flash download intercept,
and that's not the case. Maybe I should rename it to
FlashDownloadUrlInterception? Let me know what you think.
