Fixed setFrequency
- In setFrequency(), _frequency[timer] is stored as the actual frequency rather than the desired frequency. This change is propagated to setPeriod(), which calls setFrequency(). This affects the values returned by getFrequency() and getPeriod().
- In bestClock(), the formula to compute the error was scaled to the divisor ratio for a more meaningful comparison.
- Encoding mistake generated by bad characters... (Version 1.4.3 was broken)
