default config to close window instead of close and kill

[daedhel]

Hi,

In the default config, there is an example keybind to close than kill a program (bspc node -k), but no example to only close the window (bspc node -c).

Closing the window without killing the program is desired for example when closing an uneanted dialog.

It would be great to add an example for closing a window without killing the app in the default config.
