From 57b8f340a6689fafd0c8d92aebd2b263b090af18 Mon Sep 17 00:00:00 2001
From: Markus Heiser <markus.heiser@darmarit.de>

Subject: [mod] utils/searx.sh - add command 'inspect settings'

Inspect YAML setting <key> from SearXNG instance (${SEARX_SRC})::

  utils/searx.sh inspect settings server.base_url

utils/lib_install.sh
  should not log on stdout which is used for the output of function
  prompt_installation_setting().  Turned build_msg (stdout) into
  info_msg (stderr).
