Proposed fix

Here is a patch: most of the invasiveness is UI.

-It adds to the curve dialog a combobox to set the interpolation policy:
Y axis, X axis, highest resolution, and lowest resolution.  A combo box was
used because radio buttons don't have a tri-state option.

-The default in the UI is now 'Y axis' rather than highest resolutions: this
alone would have 'fixed' the behavior reported in the bug. Older .kst files 
get
read as highest resolution, which was the old method.

No stickyness has been added to the new curve dialog.

Some questionable points:
-kstvcurve uses an enum for the mode.  The UI casts the enum value from the
order in the combo box - so... if someone changes the order of options in the
combo, things will break.  Alternatives are messy.
