Interrupt movement routine when desk stops moving

[abmantis]

If the desk button is pressed while the desk is being moved from the library, the desk stops. Without this change the lib will keep sending movement commands and the desk would not be controllable anymore, until those commands are interrupted.

This change makes it so that the lib automatically detects that movement has seized and so stops sending commands.
