all: I18N support

This adds I18N support using standard gettext system together
with an initial German translation. This can be used to search
locales in some directory:

Intl.bindtextdomain("shopsystem", "/home/sre/src/serial-barcode-scanner");

And this can be used to switch language at runtime:

Intl.setlocale(LocaleCategory.ALL, "");
