crecord: add an experimental option for space key to move cursor down

I really want to have an option of toggling a selection on a line and also
moving cursor down as a single keystroke. It also kinda makes sense for space
key to do this, because some other curses UIs in the wild do this (e.g. various
file managers, htop). So I got an idea to make a config option that defaults to
False for compatibility, but allows making crecord UI a lot more useful for
people with big hunks.

We add this an experimental option to experiment with this behavior.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
