More human material names

[wilcoboode]

Names get a pretty non-human readable name by default now.

Would be great if the default export name / saving of PBR material uses a name that corresponds to the prompt name. If its a long prompt, see if MuseChat can give a 2 or 3 word summary.

Also, it would be great if it saves your last saving location, or auto defaults to Project/Assets/Materials if the folder exists, as thats where you would want to save it by default imo.

Thanks for the suggestion! We have been exploring the best way to do auto-naming, however adding another request that is processed by an LLM adds a huge amount of hang time to exporting. We are testing some other methods to summarize it that work with multiple prompting formats without resulting in very long filenames. Hopefully soon
