Title: PID for heated bed

I don't know the etiquette on this, but I thought I'd start this discussion now even though the patch isn't quite ready.

I have a patch for PID and PWM control of the heated bed, with autotune support. The main thing I know is still missing is a config comment of how to replicate the low duty cycle feature that I removed, as it can be replicated with the PWM.

I also don't love that the PID code is duplicated from the extruders instead of being re-factored.

What other issues should I focus on?
