First cut a Project README file

This is a basic README file that explains everything that I just figured out about the HtF website (or at least think I figured out, let me know what I got wrong.)

I also made a stab at some suggestions for how to submit changes.

I used AsciiDoc(for) format because it's great for writing documentation and could be a good fit for HtF. (Obviously I like it personally.) It can be converted to another wiki format if someone wants to make the change.
