Is there a way to delete the mask of selected layers at once?

@Thihasoe 

Script Features:

• Single undo history step
• Applies layer mask to layer data where applicable (i.e. raster layers)
• Change applyLayerMask(true); to applyLayerMask(false); to remove the mask without applying it (line 61)
• Layers and visibility remain selected after the script is run

        DOM code doesn't have a generic adjustment layer kind, it is specific to each kind (LayerKind.CHANNELMIXER || LayerKind.COLORBALANCE etc).
        It is obviously more concise to use AM code for a generic adjustment layer check, rather than chaining together all possible adjustment layer kinds.
