Volume ignored first time sound is played about phaser

[HackManiac]

I ran into the same issue today and digged a bit deeper on this, although Rich already wrote in http://www.html5gamedevs.com/topic/445-sounds-in-phaser/#entry1993 that he is working on a rewrite of the SoundManager.

If you play a sound for the first time, it's loaded, but not yet decoded. So the SoundManager.prototype.play method will call SoundManager.prototype.decode, which then will perform two calls to Sound.prototype.play in short intervals:

1. after decoding there is a call to Sound.prototype.setDecodedBuffer, which in turn calls the Sound.prototype.play function (with the correct volume configured).

2. after step 1 the callback of SoundManager.prototype.decode is called which then calls SoundManager.prototype.play. Since only the key is given as an argument, the play function assumes a volume of 1.0.

I created a pull request for a possible interim solution until the new SoundManager is in place.

This is now in 0.9.5, will do well until new sound manager goes in.
