[Kst] [Bug 87015] plot colors can easily repeat in a plot

[C. Barth Netterfield]

'Tis tricky!

Besides the bug, there are a bunch of things to think about (wrst the wizard, 
where you have no ability to easily change the default)
	(i) should psd's and curves be the same color? (I think yes)
	(ii) how to we ensure that adding curves to an existing plot won't be too 
likely to repeat?
	(iii) do we want curve 1 in each plot to be the same color? (I think this is 
OK)
	(iv) fix this bug

Each plot with its own color sequence:
	(i) will be true for empty plots or uniformly filled plots, but not in 
general
	(ii) the curveAppearanceWidget will have no knowledge of the last color used, 
so could be bad 
	(iii) will be true
	(iv) will be fixed.

(ii) is the problem then.  The curveAppearanceWidget knows nothing about 
previous colors in the plot, so if it starts from the same place as the 
plot's color sequence, it is pretty likely to pick a color which has just 
been moved.  But if it starts from somewhere else (it will I think) then we 
are probably ~OK. 

The command line needs to use the color sequence from each plot.

So: a color sequence for each plot, used by the command line, the wizard, and 
to populate the fit and filter dialog, and a global color-sequence for all 
the other dialogs (should start at ~+6 or so - which it will automatically).

We can try this.  The question is whether we should try it for 0.99 (what we 
have now ~works) or wait.

thoughts?
