add expirity headers to enable caching of the 404 for undesired favicons
attempt at adding a test for bounce_icon
fix wording and naming. oops.
Added a couple of fixes (had the wrong name for the class), and a test.
I can't actually test the test, because ruby 1.9 doesn't want to work with specrb for some reason.
Anyway let me know if the test fails on a system that can run it.
open for 2 years (wow. seems like not that long ago).
Closing because nobody cares about it.
