Fluid 5004

I've updated the build site in the following ways:

* Added a README.txt
* Corrected in the information in the footer
* Removed dead links
* Added missing links
* Restructured the layout of the content
* Removed the manual-tests.html and moved the links to index.html
* Provided a index.html with a custom build of Infusion to source the FSS style sheets from, rather than relying on the built versions for these.

The remaining task for this issue will be to have the server automatically update from the master branch of this repo.
