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.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.

            return res
