[EXAMPLE:F0] Add example of using systick and MCO output on pin PA9.

Browse Source 
This example is a merge of Chuck McManis's example for F4 and onnokort's system clock setting test blink example for demonstration issue, corrected in #224.

The LED in any available clock setting flashes four times per second.

This example is the same as fancy_blink except that it uses the systick timer
to generate time accurate delays. The blue LED flashes four times per second.
On pin PA9, there is MCO output of internal reference clock. This can be used
to debug the PLL clock setup by scope.
