Reddit Image Download di Zawaro

Adds a Download button to Reddit post pages that saves images in their original quality directly from i.redd.it, bypassing Reddit's compressed WebP previews.

Features:
- Original quality — Downloads from i.redd.it instead of compressed preview.redd.it WebP
- Gallery support — Downloads all images from gallery posts in sequence
- Image probing — Checks image availability before downloading (catches deleted/expired images)
- Save As or Silent — Choose between a save dialog per image or automatic download to a configured folder
- Customizable filenames — Formats: post title, subreddit+title, or image ID
- Folder organization — Use variables like {year}, {month}, {subreddit}, {author} in folder paths
- Settings panel — Configure download mode, folder patterns, filename format, max title length, and debug logging from the options page
