Bill Somerville 85c4f6722b Add user defined waterfall palette.
The  new  class WFPalette  encapsulates  waterfall palettes  including
exporting and importing to disk files and interpolation for use in the
waterfall plotter.

A special  entry in the palette  list "User Defined"  is now available
along with  a button  to invoke a  colour palette designer.   The user
defined palette definition is persistent across runs as it is saved in
the application settings file.

Palettes can now have any number of colours up to 256.

The export function may be used  to save user designed palettes; to be
added  to the built  in resource  palettes that  are shipped  with the
application.
