- Added QF_SCALEUP and QF_MAX.

- QF_SCALEUP behaves like QF_SCALEDOWN: it gradually scales the tremors, only going upwards.
- QF_SCALEUP and QF_SCALEDOWN can be combined to make an earthquake that gradually smoothes in and out.
- QF_MAX can be used to invert this behavior, where it starts at the peak of the amplitude, fades out half way, and then grows back to maximum.
