feat(config): allow multiple asc files

This commit allows either the single canonical applications.json file,
or multiple files which adhere to the asc scheme to be given to the
app_specific_configuration_path config option.

I thought I had already implemented this earlier, but evidently I
hadn't.

This will be useful for people who want to maintain their own
independent set of asc rules, as they can be kept in a dedicated file
which won't be overwritten by the fetch-asc command.
