remove c_k c_n mappings, see vimoutliner#128

Don't set the mappings by default, instead
mention the possibility and how to do it in
the documentation.

Replace earlier mentions with the default
CTRL-] vim mapping.

Remove the Q mapping from the cheatsheet and the
documentation. It is not set anywhere in the code.
