Fix for GenerateScraperGraph

[epage480]

Created a fix that allows examples/openai/script_generator_openai.py to run successfully.

I made 3 major changes:

1. Added a new parameter "parse_html" to the node_config for ParseNode. If set to False it will give the unparsed html, which is useful for creating parsing scripts. Default behavior is identical to before.
2. Removed the RAG node from the ScriptCreatorGraph, RAG for HTML is a non-trivial task and was not being done well.
3. script_creator_graph.py contains a lot of dead or non-functional code, it appears someone attempted to use RAG unsuccessfully.

While ScriptCreatorGraph will fail for websites with a high token count, these changes will allow at least some functionality and a starting point for expansion.
