Please allow libwww-mechanize-ruby 0.6.3-2 into testing

[Ari Pollak <ari@debian.org>]

Hi release team,

libwww-mechanize-ruby 0.6.3-2 contains only two changes to fix RC bug #405027,
which required adding dependencies on libopenssl-ruby1.8 and
libopenssl-ruby1.9. I'd like to request that this be moved into testing.

Thanks,
Ari
