Adds cover_url and banner_url to API , fixes blades

[sometimes-coding]

Expects url hence cover_url and banner_url, no change has been made to http/TorrentController.php which could probably benefit from this change as well (though you may want to add it as additional option rather than replacement)

Considerations: Imagick needed for compression (if enabled) , better support for varying filetypes while preserving alpha channels if applicable.

Conversion to .webp its old news but lets optimize storage, load times and leverage capabilities to include transparency for applicable no_meta categories. (yes, I've made sure it can grab .jpg for backward compatibility)

Whats with this UrlHelper??

I'm a php baby, so might be a better way to implement this. The idea is to try to keep things read-only so externally hosted is great. However not so reliable. DMCA's anyone? So while whitelists is great for hosting screenshots and whatnot, having nuked covers and banners might not be ideal. Thus this would be a helper where you can configure trusted external hosts (that wont be here today, gone tomorrow) and just display 'em if trusted. Else, we can just download the image, compress and serve it. Obviously safeguards need to be in place so this feature should be able to be turned off. Also could skip download if content-header not known to prevent abuse.

Hope this helps with Issue (#3897)
