Leaving %discnumber% blank for single-disc albums?

[Uoppi]

Foobar2000 makes it pretty easy to filter out the single disc albums for masstagging, so no problems there.

I'm quite happy with this solution. At least in BubbleUPnP Android, there are situations where it's not easy to tell, which disc of a multidisc I'm looking at (for example, in the "Recently played" list), unless the disc number is prefixed to the title by MinimServer. And now - just as conveniently - if nothing is prefixed, it tells me straight away the title comes off a single disc album (and some screen real estate is saved too).
