    BUG FIX: Flags CY and AC were not clear by logic instructions
    Added new flag to microcode: clr_acy
    Used new flag to clear AC and CY flags unconditonally
    Modified microcode for XR*, OR* and AN* to use new flag
    Modified microcode assembler to support new flag
    Addex explaination of new flag to documentation
    Old fix that worked only for XR* instructions removed
    Test bench tb0 modified to test CY clearance minimally (AC untested!)
