feature request: disable 'accept all' in settings

[fredvd]

The 'accept all' button on the detailed privacy settings modal is a bit of a dark pattern: if visitors have clicked on the 'change settings' in the previous step, it is very unlikely that they want to accept all settings again. 'Update my preferences' and 'only necessary cookies' would be enough.

If would be cool if that 'accept all button' can be make optional in the add'on settings.
