makeSolidChainsSpt()
	colors according to solidColorScheme by calling makeSolidColorSchemeSpt()
	then calls makeSolidRenderSpt() which does spacefill and applies colorLigand, colorSolvent.

makeRenderSolidSpt() was the default currentView at startup.
	It spacefills only (no coloring).
Default startup changed to makeColoredSolidSpt().
