This patch adds the ability to set the SCK period on the STK500.  I needed this because the mega48 comes from the factory configured to use the 8 Mhz internal oscillator divided by 8.  This results in a max SCK frequency of 250 kHz.  Changing the oscillator frequency via the STK500 fosc command doesn't help, as it has no impact on SPI speed in this case.  Reducing the speed of SCK allows for reliable SPI communication between the STK500 and the target device.
