Ellipses -> Ellipsis rename (the dictionary really says that it should be Ellipsis!). Bumped the API version because a linker-visible symbol is affected. Old C code will still compile -- there's a b/w compat macro. Similarly, old Python code will still run, builtin exports both Ellipses and Ellipsis.

This is my nearly two year old patch [ 400998 ] experimental support for extended slicing on lists somewhat spruced up and better tested than it was when I wrote it. Includes docs & tests. The whatsnew section needs expanding, and arrays should support extended slices -- later.
