- Made some classes not be singletons, since there's no reason why they
should be.
- Made them non-global too (because globals have unclear lifetimes, and
make it harder to test things, etc). They're now owned by CGameView and
CWorld, and mostly accessed via g_Game or arguments (vaguely trying to
avoid the graphics code calling into the game code).
- Moved CGameView implementation into pimpl, so the header file isn't
so heavy.
- Changed a few pointers into references, to indicate that they're
never NULL.
This was SVN commit r4756.
