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)

some information about it instead of simply omitting it.
Internally, struct savegame --> struct savegame_ for easier grepping.
