Accel Charge item v0.9

A special item that will decrease charging time for your arm cannon. A replica from Other M. After obtaining Charge Beam, you can charge your beam very slowly. After collecting each Accel Charge item, the charging time will decrease in this order:

Amount Time to charge (s)
------ ------------------
0 2.00
1 1.75
2 1.50
3 1.25
4 1.00
5 0.75
>5 0.50

This is an unfinished version. Altering charging time is working fine, but sparks coming out of your cannon aren't tweaked yet.

Changes since 0.8:
Bug is removed and unused free space in the end of bank $91 is cleaned up.

Bomb Spread attack timer and Pseudo Screw Attack timer are tuned to amount of Accel Charge items.

No item icons, sorry. But I have provided addresses at where you can draw them.

Menu isn't altered.
