Editor Client with some simple patches to be used by ESPHome Nodes.

Features Added:

• Enforced flow specific scope of config nodes (we are using config type nodes for components like inputs, so we can't let them be shared globally or to other flows)
• Nodes can have multiple inputs (since we are using the Node-RED editor-client without an active runtime, to model automation flows between inputs and outputs, we don't have to fear the implications of msg's traveling to multiple inputs)
