Allow increase in timeout for USB drives

I run greyhole on my Plex Server. It seems when I play the first item my USB drives are just a few seconds too slow for plex. This results in the media becoming unavailable. I then have to go back and forth to play it. This is fine for me, but people who I’ve shared with won’t know the technical issues behind why the media isn’t playing. Give up and leave.

So inside Preferences.xml a timeout option would be appreciated IE <mediatimeout=12000>
