added support for recording nq demos, but only if not already on the server.
added capturedriver as a sane way to select between screenshots, avi, or various plugins.
output sound device can now be selected via the menu. not all drivers provide device enumeration (openal and dsound do).
enabled openal, but not using it unless an openal device is explicitly requested as its still a little buggy.
added \"\"" markup in the console.
