build: break the engine into its subsystemsv0.60
Break the source code into various subsystem directories. This allows
certain subsystems to be disabled at compile time, if needed. Move the
build system from raw Makefiles to a CMake generator. This drastically
simplifies the build and requires only editing a single file, rather
than the several make.config files in subsystem directories.
