5.0.1 = 404

While I finish rebuilding 6.0b1, a parenthetical note that there will be no TenFourFox 5.0.1. We aren't affected by the font issue on 10.7, obviously (and the code is riskier on 10.4), and the 10.5 Java issue can be worked around using the Terminal tips in bug 668639. Since releases are expensive for us, a single workaround-able issue is not enough to force a new version on our end. While I will revise the 5 changesets to deal with the font issue changes, that will occur after the beta comes out, or they can be applied to the original 5.0 source tarball instead of the current hg tree tip.
