[airstrike] Compilation Errors

I changed the CVS makefile so that the produced binary is again
named 'airstrike' instead of 'testengine' (as the upper level makefile
expects).

I also added sound support back in:
- sound effects are now defined in engine/sound_fx.[ch]
- changed core/sound.* to accept the sound position as vector_t instead
  of two ints:
  - changed biplane.c, bird.c & bullet.c accordingly
- sound support in makefile
- sound is now on by the default

Ulf, I think maths.[ch] and array.[ch] could be moved to core/, there's
nothing Airstrike specific in them.  What do you think?

Hm.   I could make a temporary snapshot out of the stuff if somebody
is interested.

The main problem at the moment is that there's only one plane.
Otherwise I think the game is now better than earlier.
