Add an ability to MOVE/SWAP channels

Currently, when I want to move everything from one channel to another, I need to copy the source channel to a desired position and then intialize the source channel. Those are two operations with a bit of chaos in between.

The FR is to be able to move a channel from one position to another, with all the settings, in one single operation. E.g. the LS9 does this by swapping the channels so nothing is deleted/initialized.
