NextClouPi gets a Web Interface

Hi everyone,

I am happy to announce that NextCloudPi now features a web UI for things like setting up Let’s Encrypt and other extras.

I reused like 10% of nextcloud/server core.css code. Credit is given in the code, and I think that the AGPL license allows this, but if there is any issue with this, please let me know.

Feedback is welcome, specially regarding to potential security issues (private please).

The ARM docker image automatically inherits this, so I will now proceed to building it as well.

AGPL allows you to use up to 100% of the code !
