Allow disabling LinkHints for specific sites.

[hi-im-buggy]

Problem

LinkHints overrides the keyboard shortcuts for some sites, such as Alt F for WhatsApp's quick search feature. While this could be 'fixed' by changing shortcuts for LinkHints, that might conflict with some other website's keyboard shortcuts too. LinkHints is less useful than the website's built-in shortcuts in some cases.

Suggestion

Allow disabling LinkHints for specific sites, ideally as a list with regex support for matching the URL.
