[safebooru, danbooru] Incorrect names given to ratings

[scoliono]

Bug description

Safebooru and Danbooru rating descriptions shown on the websites do not match the abbreviations given in the API. Grabber takes this value directly from the API, potentially affecting the save location of images.

Steps to reproduce

1. Search id:4054397 on Safebooru

2. Click 'Details'

3. Rating shows as 'questionable'

4. Search id:5450477 on Danbooru

5. Click 'Details'

6. Rating shows as 'g'

Expected behavior

In both cases, the rating should show as 'general' like it does on both websites:
https://safebooru.org/index.php?page=post&s=view&id=4054397
https://danbooru.donmai.us/posts/5450477

I suggest adding a setting that configures how ratings in each booru's API get mapped to a %rating% value. The current categories seem to be pretty unreliable anyway. For instance, Gelbooru just made a new 'general' rating and renamed 'safe' to 'sensitive'.

System information

• OS: Arch Linux
• Grabber version: 7.9.0

Additional context

According to the Safebooru api, 'q' means 'general' and 's' means 'safe'

So from what I understand from this post on Danbooru and this post on Gelbooru:

• g (general) => new 100% SFW, "extra-safe"
• s (safe) => s (sensitive)
• q (questionable) => no change
• e (explicit) => no change

Do I get that right?
BTW, will safebooru now only contain "general" level images? 🤔

[Bionus]

On safebooru, the rating is incorrect because their API returns "rating=q" for this image:
https://safebooru.org/index.php?page=dapi&s=post&q=index&limit=20&pid=0&tags=id:4054397
I guess it's not all very ironed out yet on their end.

I'll fix the "g => general" mapping at least.

According to the Safebooru api, 'q' means 'general' and 's' means 'safe'

It doesn't really make much sense, given "q" is an already existing shortcut for "questionable". Is this Safebooru-specific? 🤔
