[Cuis] Minor Updates

[KenD]

For those interested in performance, I have updated the Cuis-Ropes README with some notes.

I also optimized #do: to avoid multi-level indexing.


Cuis-Soltaire also now supports both drag 'n drop behaviors.  
	Mouse-down, drag, mouse-up to drop
and
	Click to pick up, move-mouse, click to drop
[Thanks Juan for new D&D updates!]

I still have to rewrite redo in Solitaire, but my inclination is to work on giving Ropes the full String protocol.  We shall see!  ;^)

Cheers,
-KenD
