A suggestion for the glfw target. To change the OpenAL/ gxtkAudio initialization from:

	if( alcDevice=alcOpenDevice( 0 ) ){
		if( alcContext=alcCreateContext( alcDevice,0 ) ){
			if( alcMakeContextCurrent( alcContext ) ){
				//alc all go!
			}else{
				bbPrint( "OpenAl error: alcMakeContextCurrent failed" );
			}
		}else{
			bbPrint( "OpenAl error: alcCreateContext failed" );
		}
	}else{
		bbPrint( "OpenAl error: alcOpenDevice failed" );
	}

To this, which will work if alcOpenDevice(0) fails for some reason:

	alcDevice = alcOpenDevice( NULL );
	if (!alcDevice)
	{
		alcDevice = alcOpenDevice("Generic Hardware");
		if (!alcDevice)
		{
			alcDevice = alcOpenDevice("Generic Software");
			if (!alcDevice)
			{
				bbPrint( "OpenAl error: alcOpenDevice failed" );
			}
		}
	}
	
	if (alcDevice!=NULL)
	{
		if( alcContext=alcCreateContext( alcDevice,0 ) ){
			if( alcMakeContextCurrent( alcContext ) ){
				//alc all go!
			}else{
				bbPrint( "OpenAl error: alcMakeContextCurrent failed" );
			}
		}else{
			bbPrint( "OpenAl error: alcCreateContext failed" );
		}
	}

Ok, easy enough to add - but does it actually solve any known problem?

At least in one machine at university, the desktop target just "blinked" on screen - OpenAL was failing since the installed driver was a "default" one on Windows 7. With that, I could get the window to stay opened. (Couldn't render anything since it couldn't run OpenGL properly either, but that's a poor Intel driver problem ^_^)
