OpenClaw: reimplementing Captain Claw

OpenClaw is a C++ reimplementation of the 1997 game Captain Claw. It uses SDL2, Box2D, and TinyXML, and reads the original CLAW.REZ archive from Build_Release. The assets in Build_Release/ASSETS are zipped to ASSETS.ZIP. Windows can open the Visual Studio 2017 solution or run cmake -G "Visual Studio 15 2017". Ubuntu installs the SDL2 development packages and then runs cmake and make. An Emscripten build produces openclaw.html, openclaw.js, openclaw.wasm, and openclaw.data.
