Banshee branched for 1.6.1: stable-1.6 branch

[Gabriel Burt <gabriel burt gmail com>]

Hey translators!

We have created a stable-1.6 branch that we'll release 1.6.1 from at
the end of April.  It should remain string frozen, so feel free to
translate it.  Active development for 1.7/1.8 will be taking place in
master.

Thanks!

Gabriel
