Tube: reconstructing the 1994 DOS game source

This recreates the source of Tube, the 1994 DOS game from Bullfrog, using Hex-Rays and IDA Pro. The result builds as a 32-bit program with SDL2. Windows uses build_windows.bat, Linux uses build_linux.sh, and the web build uses build_web.bat. The README also lists OpenWatcom 1.9 for a DOS DPMI build. It says the original code uses 32-bit pointers, so this tree does not build as 64-bit.
