Fixes a bug that could have caused spurious statuses for certain urls (caused by containing a percent symbol which isn't part of a percent-encoding, which is a bad practice anyway.)
Fixes some urls with unlikely character combinations in the querystring or path to misleadingly display in tables as the domain only
Some social and calendar 'add this' links are now listed but not checked. It's potentially not a good thing to request these urls to check them. They are major domains (eg Google, Outlook) and tend to be generated by plugins, and so more likely to give a false positive when tested than to actually be broken.
