A few misc changes

A few misc changes

	* 09-sounds-sy.el: Re-enable PulseAudio.

	* 13-misc-sy.el (default-frame-plist): Give it a name "SXEFrame"
	so I can have different Sawfish window rules the initial frame and
	subsequent frames etc.

	* 16-riece-sy.el (sy-riece): Set frame width.

	* 17-emchat-sy.el (emchat-use-sound-flag): Re-enable PulseAudio,
	also set `default-media-stream-volume' to 50 so it doesn't blast
	my ears off.
