Changes

BD25 MC_SET_INKS ;in: DE=ptr to border and 16 inks (17 bytes)

These functions are directly accessing I/O ports. WAIT_FLYBACK is eventually useful. The MODE/OFFSET apply the new setting to the hardware (but the BIOS functions like TXT_WR_CHAR aren't aware of it; so they do still draw pixels at the old offset and old color depth). The INK functions expect hardware color codes (eg. 14h or 54h for black), and, the infamous blink-feature will overwrite the new colors after soon.
