Many, Many fixes

First, when testing the Frameset layout in Safari, I noticed the
activity manager was showing the `jwplayer.js` as being `Not Available
on this server`. Then I looked and saw that the script was being
referenced directly (#facepalm). After linking it relatively, which also
allows offline playing, everything loaded fine.
I added #8, all I've done so far is make another Links page that uses
anchors instead of buttons. The frameset can be bypassed by
middle-clicking the links.
A few layout optimisations i.e. removing unneccesary line breaks.
Removed `loading.htm`: Redundant page
Added link to Frameset page, added extra image align tag
The blank page basically inherits the `main.css` stylesheet, and
displays message in a quite large font size on how to fix your
JavaScript settings (if they are disabled).
