Open1560: partial reconstruction of Midtown Madness build 1560

Open1560 partially reimplements Midtown Madness Sneak Preview Beta build 1560 in C++, retaining assembly for functions not yet rewritten. Its source adds an OpenGL renderer, controller support and fixes, while its methodology notes identify builds and discuss disassembly. Running it requires data from a user's installation of the original game.
