[rox-devel] updated polish translation

[madman <ma...@bo...>]

Hi!

I finally managed to subscribe to ROX Filer mailing list ;)
I've been using rox for several years now, and I constantly had to correct
the polish translation. Don't know if my updates ever got to rox packages,
but I hope now it will ;)

Polish translation is horribly outdated, thus included is an updated one,
featuring more translated strings, and a bit more sane-looking polish
interface ;)
