Rewrite the savegame format in terms of the generic saving/loading system.

This makes savegames practically the same as the initial snapshot of a demo.
Saves are now named 'dukesavX.esv' (demos: 'edemoX.edm').
Additionally, many changes that couldn't/needn't be cleanly separated are added
with this commit:
 - make spriteext_t have the same size across 32/64 bit platforms (actor_t partially)
 - prevent saving/loading in MP games (it certainly didn't work and still doesn't)
 - it's time we start using assertions! Define NDEBUG for releasse builds.
 - reset savegame major and minor versions (we have a new magic string, so no conflict)
