feat(main): Language setting in config file

Load localization according to either the environment or the
configuration file from the list of supported locales.

Ideally, we would also set the chromium locale with --lang, but by the
time we have read the config file (to known which locale to set),
electron has already initialized the chromium resource bundle.
So the chromium localization will always be auto-detected by chromium.

Also makes startup hopefully a bit faster by doing more things
concurrently while the localization and the main window is being loaded.
