2.0.0 (2020-06-20)
(Apollon77) check object and not state to detect if an object exists
(jwiesel) Updated settings.js to incorporate latest changes up to Node-RED 1.0.6
(jwiesel) Replaced HTTP basic authentication by Node-RED login form (adminAuth)
(jwiesel) Replaced MD5 password hashing by bcrypt.js as recommended in the Node-RED security guide.
**(bluefox) Hide the palette manager so all the packets must be installed via ioBroker configuration dialog**
Caution: For those who already used Node-Red authentication: Please set your password in the Node-Red instance settings in ioBroker again! Otherwise you cannot login to Node-Red any longer after the upgrade
