Pages: Moved imagebar to inter-page space, fixed noscript displaying

Tweaked some things here and there, and removed that JQuery junk I was trying to use in order to keep the imagebar upright and outta-sight.

As a side note, as @yuriks mentioned, we aught to create a repo named "citra-emu.github.io" and move the gh-pages there. It'll cut out on the PR spam at least, and it'll allow us to have the page on the subdomain itself instead of on a subdir of our subdomain.
