WebUI to manage OrbitDB and databases

OrbitDB should have a WebUI app through which OrbitDB instance can be managed.

This would include:

• Create new databases
• Query databases
• Add databases to replicate
• Network and connection status
• Display database information, such as: data directory info, keys, size (bytes or entries), replication status, etc.

At the moment, as we don't have a daemon nor http server, this could simply be a browser app where OrbitDB is embedded. Later on, we can serve the WebUI via a daemon or http server and connect to and manage a "backend / server" instance of OrbitDB.

This is a fairly large task but also not hugely complicated and would be a great task for someone looking to contribute in a big and meaningful way! If you want to work on it, comment here.
