make updated readme markdown with links

I think it's best to make the README you see when you get to GitHub tell you what you're looking at and be in MarkDown.  Here's a basic idea, but you might want to make some changes.

The links I provide aren't ready yet because I'm using version tags and branches that don't exist.  I don't know if you wanted to call this **v1.1.0** or what, but that's the (not yet working) tag name I used.  You could also call it **v1.0.5-soren** or similar.  A tag is just an abstracted name for a commit ID, so even if a commit gets rewritten the tag can be updated to a new number.

Anyway, once you do a pull request of develop into master on DDS that can be labeled v2.8.0.  And once that label exists, the submodule for DDD can be stamped with that tag to retrieve it.  Then we stamp this with its version number.  Then you go to the releases section, edit the release notes, and add any binaries you like and it will say "released by Soren Hein" instead of by me.  :-)
