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.
