[stella] INV+ Release Candidate 4 - inv41904.bin

[Erik Mooney <erik@xxxxxxxxxx>]

Thanks to Albert for testing this and catching some problems. :)

Changelog 04/19/04:

- REALLY fixed the bug where one missile could hit two fast-moving
invaders.  (The code to check it was there, but in the wrong place.)

- REALLY fixed the bug where sound effects could get stuck.

- Tweaked the saucer noise; it now sounds less piercing and a bit more
like the arcade (in MAME at least)

- Saucer doesn't make noise if it appears while the game isn't in progress

- Increased the delay between player shots slightly.  This makes it closer
to the arcade gameplay, and makes it a bit harder to accidentally
repeatedly damage a shield (which is also a factor when you're counting
shots for the saucer score.)

I'll be able to give this some extensive testing on real hardware in
2-player mode tomorrow, and then I think it'll be ready for final release.
Any other comments and/or testing are welcome, as always.
