audio::mpd 0.19.5 released

audio::mpd 0.19.5 is on its way to cpan.

changes:

• updates to match mpd 0.14 behaviour (released for x-mas)
• doc update

the new idle command is not (and will not be) implemented in audio::mpd, since it requires non blocking sockets and i don't want to deal with them in this module. it will be implemented in poe::component::client::mpd, though.
