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).
