Dist name not right in metadata

Hi George,

The Makefile.PL for this dist was setting the distname to Selenium::PageObject instead of Selenium-PageObject. This mean that the distname in the metadata didn't match the distname as worked out using CPAN::DistnameInfo (which works it out using the release filename).

I also updated the Changes file to use the most widely used format (defined in CPAN::Changes::Spec).

And there were two URLs in the SEE ALSO section that didn't have L< ... > around them, so they're not appearing as hyperlinks when you look at the doc in MetaCPAN, for example.

Cheers,
Neil
