Merge pull request #21 from AbigailBuccaneer/gh-pages

Add stylesheet to manual.
Added my manual version, feel free to modify it.

It uses a page format where you simply add another <div> with id="page#" where # is a number.
You then go ahead and set the number of pages in the script.js file.

I have copied over most of the style from the current manual, so it works roughly the same.
Cleaned up abit

Added paper texture background.
# of pages is now detected automatically.
Updated contents and style of the manual.
Moved all images to a separate directory.
