Serum: ENV background text

Hi there,

Steve, would you mind to implement a swtich to the ENV windows to see a bpm synced text background? I mean, I want to see e.g. "1/4" or "1/2" grids in the background instead of "1s". Or just a switch which switches that text behaviour on to of the knobs. That would be very handy!

I know, there is not that much space in the GUI left, but I'm sure you can do that! :)

It's best to use the LFO like an envelope when you really need something tied to BPM. Unfortunately this request gets a bit deeper than it first may appear, but I've added it to the requests pile.
