Separate Fader locks

This request is for the global setting for Fader Lock to have a sub-setting for each individual set of pages. AKA tick boxes to be able to select Level, Envelopes, Pitch, Loop/Slice individually so that those could be locked on machine startup and others would not be by default.

This came up for locking loop/slice in particular so that the sample start point does not jump accidentally.

There is a slightly different request than the existing one to be able to lock individual track faders.
