Subject: [PATCH] extensions-tool: Set up translations for standalone builds

While we can now build gnome-extensions-tool as stand-alone project,
we are currently missing any translations, as those are part of
gnome-shell.

The easiest option for addressing this would be to symlink the toplevel
po directory into the subproject, however that would mean duplicating
the entire gnome-shell message catalogs.

So instead, set up a bare po directory and provide a script to populate
it from the translations in the toplevel po directory.

+## Building
+Before the project can be built stand-alone, the po directory has
+to be populated with translations (from gnome-shell).
+
+To do that, simply run the included script:
+```sh
+$ ./generate-translations.sh
