Fusion: reconstructing Rovio's game-engine libraries

Fusion reconstructs Rovio's multiplatform game-engine libraries, chiefly using the iPhone Angry Birds Seasons v4.1.0 executable and its debugging information as references. Its CMake project builds much of the recovered library code for Windows. DRM and in-app-purchase implementations are outside the project's stated scope, and other build types remain unfinished.
