Automatic output mode selection

[martindevans]

By default the OutputMode of the sound system is automatically selected. However, this causes strange lockups of the sound system on windows 10 (it seems as though FMOD takes exclusive use of the sound device and never releases it).

Current hack to fix this is:

if (!SupersonicSound.Wrapper.Util.IsLinux)
    ll.Output = OutputMode.DirectSound;

I'm in Win10 and didn't experience any issue with the default/automatic selection. I ran without the IsLinux test first (just commented out the OutputMode) and it worked fine and didn't lock up the Windows sound device. At least not here on my machine.

I added the IsLinux check to leave it as-is in Windows because I figured there was a reason you picked DirectSound.
