Add an optional keyword argument to lua_compute_context to control
whether the author's note should be included in the context. The
default value is true, so if the include_anote kwarg is not specified
then the author's note will be included, which was the default
behavior prior to this change.
Also update the Lua API documentation to describe this kwarg.
Moved examples to their own example directory, treating folders we didn't add as a unofficial folder, anything in examples gets submitted in commits. Because I want people to learn that kaipreset_ should only be used if a file should be part of KoboldAI's official scripts the examples do not have kaipreset_ in the name.
