Introduce app id

For now, if the user wants to fix only google chrome, he must go to the database list and then figure out the file name in order to fix it.

The best way to handle this is to introduce an app id; which will be listed with a new variable argument in two columns, the app name, and the app id. So the user can easily figure out how to fix only one app, or how to add an application to the blacklist. This will require some rework, so it won't happen in the next milestone. Maybe a little bit later.

No files, tests, or entry points are named. Start by locating the database-list, application-fixing, and blacklist workflows, then define how an app id is displayed beside the app name and used to target one application; done means users can identify and select an app without discovering its filename.
