Game List: Less innerHTML, more DOM manipulation

I'm concerned that using innerHTML to write user data to the page risks someone
injecting quotes into a title and unintentionally mucking up the game list.

This method should avoid that since the only text we now pass to innerHTML is
entirely our own creation and any external strings are added to text nodes or
directly to element fields where they won't be interpreted as HTML.
Game List: Switch to JQuery 1.x to work with IE 8

JQuery 2.x only works on IE9+, but I don't need any of it's new features, so
switch to 1.x which supports older IE browsers.

Can't go too old though - IE 7 and below don't seem to work with the method I'm
using to talk to the Blogger API - no idea if I can do something about that...
Game List: Remove explicit Kerbal Space Program equivelence

Looks like someone fixed the title, so I no longer need this rule.
