Fix player possessives, and improve hyperlink detection

FanGraphs will sometimes include the apostrophe inside the hyperlink,
resulting in a wikilink like "[[Joey Gallo']]s foot". We move it
outside, resulting in "[[Joey Gallo]]'s foot".

Support hyperlinks to old FanGraphs player pages, and hunt down links
a little better.
