- update version to 2.1.1

- node description updated
- node now errors if msg.host or msg.port is left blank and not configured on the node
- server type & host is not required when configuring the node since it can be passed in via the inputs
- when modifying a node in the editor you can now view available server types at the bottom of the properties. This is parsed from the gamedig readme.
- Update gamedig version
- package-lock.json added
- palette label changed to "Query Game Server"
