Add Sophia - an assistant within the node editor

[bashybaranaba]

The idea behind Sophia is to add an assistant in the node editor who can help users in the process of creating world workflows.

For this, a chat interface that would be either a collapsible or a dialog will be included in the Node Editor interface where the user can interact with Sophia through text prompts.

Sophia should have access to the current state of the node workflow the user is currently to properly assist and collaborate with the user in creating the workflow.

The assistant can provide suggestions which then a user creating a workflow can accept by clicking an "Accept" button which will allow the assistant to make direct changes to the node workflow, using a similar prompting logic used in the "godprompt" that allows the users to create workflows from a prompt
