Enable different colors for oscilloscope channels (#7155)

Browse Source 
Enable to set different colors for the oscilloscope channels:
* Left channel color
* Right channel color
* Color of all other channels

The clipping color is now used per channel, i.e. if the left channel clips but the right does not then only the signal of the left channel is painted in the clipping color.

Enable setting the colors in the style sheets and adjust the style sheets of the default and classic theme accordingly.
