[Mailman-i18n] new language for 2.1(b)

[Barry A. Warsaw]

Send them to me, preferrably as a tarball that I can unpack in the top
of the source directory.  That means your tarball should have a
messages and a templates subdir with the appropriate subdirectories in
there.

Please also send me patches to Defaults.py.in for Serbian.

May I add your name to i18n.html?

And thanks!
