Get/Set configuration script source

-- Invoke with 'nvim -l get_conf.lua conf_name'
-- Where 'conf_name' is:
-- - one of the entries in lua/configuration.lua
-- - the keyword 'config_home' to get configuration location info
-- - the keyword 'list_names' to lists all configuration entry names
-- - an option/variable name to retrieve its value
--
-- For example, to retrieve the Lazyman configuration 'namespace' setting:
--
-- #!/bin/bash
-- NVIM_APPNAME="nvim-Lazyman" \
-- nvim -l ~/.config/nvim-Lazyman/scripts/get_conf.lua namespace
--
-- or, to retrieve the value of the 'mouse' option in the Webdev config:
--
-- #!/bin/bash
-- NVIM_APPNAME="nvim-Webdev" \
-- nvim -l ~/.config/nvim-Lazyman/scripts/get_conf.lua mouse
