Super Mario Bros. 2: SMB2 Improvement

This is designed to fix a few small things without changing the game too much.

List of Changes:
* Restored the sound effect that's supposed to play when you die. It never worked due to a bug.
* Restored the missing 8th animation frame for tiles. It was never shown due to a bug.
* Swapped names for OSTRO and BIRDO in the credits.
* Changed PRINCESS to PEACH in credits and "contributor" text.
* Changed "PUSH START BUTTON" to "PUSH START".
* Changed "PUSH (A) BUTTON" to "PRESS BUTTON".
* Changed CLAWGLIP to CLAWGRIP in credits.
* Changed HOOPSTAR to HOOPSTER in credits.
* Changed TRICLYDE to TRYCLYDE in credits.
* Fixed issue where doing a charge jump makes you throw an item.
* Fixed POW graphics (The "O" was offset by one pixel in one frame).

Description:
This is designed to fix a few small things without changing the game too much.
I've used the All-Stars and GBA versions as somewhat of a reference, changing
what I feel isn't too different, but an improvement. This could be a nice
base for other small hacks.
