[Cuis-dev] Fix for nil cursor

[Phil B]

I went with lazily initializing the cursor instances because only ~1/3 of
them ever get used in normal operation.  I think the rest of them date back
to ST-80 but are no longer used.  So this way they're still available for
anyone interested and out of the way for everyone else.
