+ Add SCI_SETCOMMANDEVENTS API to allow turning off command events as they

Optional indexing of line starts in UTF-8 documents by UTF-32 code points and UTF-16 code units added.
This can improve performance for clients that provide UTF-32 or UTF-16 interfaces or that need to interoperate
with UTF-32 or UTF-16 components.
