New Technology Kickoff

After a lot of frustration with the old technology stack, I moved to a new one. This release is based on the Urho3D engine. A lot of thanks goes to the creators of this nice tool! Also the API has been streamlined, instead of experimenting with multiple different API choices, this release contains a binding, which is now more simple and the resulting API should be clearer.

One final remark: the complete project is a hobby project as you can see from the limited activity on Github in the last year. HGamer3D is not a production ready SW and it is not clear when or if at all this will be the case. Sorry for that but it is important to get this clarified.
