Added a scraper for CivitAI posts. Only supports post URLs (not single images) due to API limitations. API also does not provide the "description" visible on the site itself. Meta information like model, prompt, seed, etc. not used as we do not (yet) has a way to store or show this neatly.
* add bluesky scraper
