HotSheet Project Page Upgrade

The project page for HotSheet has undergone an upgrade. This is the new format I’ll be using for all my project pages in the future so I can include the exact same ReadMe.html file in the project itself and use it on the website. That will make sure that all the data is kept together and organized together (which it hasn’t been until now) and that it is easier to get to everything, including the developer documentation, without having to download all the source.
