Updated to version 2.3.0.

It's been a really long time since 2.2.0, previous cmus release - almost 3
years have passed. During this time, Timo Hirvonen, original cmus author, has
disappeared, cmus-unofficial fork was born, and, lately, cmus-unofficial
transformed back into cmus. Long story short - here is the new release!

Features highlight:

        Gapless MP3 playback
        Native PulseAudio output plugin
        Faster metadata cache
        Improved compilation handling
        cmus-tutorial(7) man page
        SHOUTcast icy-* headers support
        Musepack SV8 support
        Support for the new libmp4v2

And, of course, tons of bugs were fixed.
