commodore64: Add 6526 2-cycle timer delay, seems to pass more tests now. CPU Dataport inputs on lower 3 bits are always high now, may fix some paging issues. Fix joystick input so that only port A is affected on pure outputs.

commodore64: fixed Ultimax E000 mapping, updated mapper 0000, added EzFlash mapper 0020 (no official games use this but a lot of disk-to-cart and homebrew do)
