Added support for multiple active layers (colored ones in the high contrast mode).

Added separate layers for pad netnames (now these are divided into multilayer/top/bottom pads).
More appropriate layers are selecting a copper layer in the high contrast mode (now it shows the copper layer itself, vias & multilayer pads and netnames).
