Follow redirects

[davesag]

Some cases, for example https://en.wikipedia.org/w/index.php?action=info&title=Weyerhaeuser_Co._v._United_States_Fish_and_Wildlife_Serv. redirect to another page. https://en.wikipedia.org/w/index.php?action=info&title=Weyerhaeuser_Company_v._United_States_Fish_and_Wildlife_Service

The parser needs to follow that redirect if it finds one.

This is an important issue because the problem is not random. The redirection issue appears to be more likely the more important the case is.
