User level installer and optimizations

A install script which installs the plugin just for the current user has been added
and the build has been optimized.

Fix Disconnect Notification

Now the NordVPN CLI asks you to rate the connection after you disconnect.
This message was also shown in the notification when you disconnect.
This has been fixed by passing on only the first line of the disconnect console output to the notification.

LICENSE added and rewritten code

This project now contains a LICENSE file and the screenshots have been moved to a separate repository.

The plugin now shows if there is no internet connection.
Furthermore it ignores update messages from the NordVPN CLI.

Finally most of the logic used to create the matches has been rewritten.

More formatting options, bug fixes, update docs

Add more formatting options for the status option inside Krunner.
