Added in some of the playlist subsystem, I've never done anything in node / c++ before so this was a fun learning experience \o/
Lets see what this travis stuff is all about :)
Added subscriber changed notification and num_subscribers function
fix some requiring sorcery for addons
more bindings sorcery
was preventing compilation
update node version for travis
Changed player to be a stream and built in stream backpressure handling so that libspotify only gives us data as we require it
Fixed memory leak by introducing a HandleScope into the music delivery process, it seems to work....
