Add ability to extract a specific argument from the URL

Add the ability to extract a specific argument from the URL into the title.

Example URL: https://example.com/?login=saml&email=test%40example.com with the title “Sign-In”

Example:

The tag could be {argvalue=”key”} with “key” being the argument key to search for to return the value. Need to consider arguements prefaced by both “?” and “&”.

Tab title format: {title} - {protocol}://{hostnameascii} - {argvalue=email}

Result: Sign In - https://example.com/ - test%40example.com

The extension is designed to be used against multiple websites with straightforward title formats. It does not offer per-website customization apart from the simple allow/blocklist mechanism.

For now I don't intend to increase the extension complexity to offer website-specific formatting or functions similar to what https://wiki.hydrogenaud.io/index.php?title=Foobar2000:Title_Formatting_Reference offers for music tracks title formatting.

Extracting a specific parameter from the sign-in URL of a specific website is inching towards that. I will consider adding the feature if there's a use case strong enough to justify the complexity.

We would also have to consider the edge case of parameters set multiple times (allowed by the standard).
