From e7cbf38af74b7841baf350ddcc85699d2295aeb7 Mon Sep 17 00:00:00 2001

Subject: Introduce a $kak_config env var containing the Kakoune user config
 dir

Makes it easier for users who want to locate their kakrc file, and
does not require to go through shell expansion to get it as
"${XDG_CONFIG_DIR:-${HOME}/.config}/kak"

Fixes #1740
