Improve link regex to fix handling paranthesis and question marks

This patch fixes two key issues:
* `?` is considered part of the URL, even if there might not be anything past it. I've seen people now putting spaces after URLs to get around this issue.
* `)` is also part of the URL, as well as `:` despite those not being valid characters at the end of URLs.
