Try to make intelligent decisions when deciding if parens should be stripped before linking

This logic is torture and needs some rework.

Rules:

• Always strip leading (, as it can't be part of a URL
• Short circuit to only strip leading if no trailing
• If valid email address when trailing ) stripped, we can strip trailing )
• If not even a valid URL without trailing ), short circuit to only strip leading
• If query parameters detected, strip trailing. It should have been encoded as %29.
• If there isn't a / the trailing ) can't be part of the URL, strip trailing.
• If there isn't at least one ( in the URI.path, only strip leading. Assume ) is not part of the URL.
• If we have an equal count of ( and ) chars with the leading ( already stripped, only strip leading
