Better linkification of TV show list's <td>

Mainly it handles cmd+click on Chrome/OS X properly - before, the link
would be opened twice, once in a new tab (default link handling) and
once in the current tab (because of the window.href change)

This should better emulate the clicking behaviour in "most" browsers,
but I've only tested in Chrome 26.0 and Safari 6.0, on OS X. What
could possibly go wrong?
