ws ec3be9a99a Replacd integer midi tick values by fractions.
- tick names a position on the time axis
- tick is always a Fraction()
- only Measure() and Segment() (and Tuplet?) have a tick value
- tick() for an generic element return only a sensible value if isMeasure() or isSegment() or isSegment(parent())

- "ticks" names a duration stored in a Fraction()
- the tick value for an Segment is relative to its measure

- rename "duration" to "ticks"
- rename afrac() to tick()
- rename rfrac() to rtick()
- rename some variables, changing "fraction" into "tick"
  (example: actualFraction() into actualTicks())

- Lyrics ticks are written as Fraction, on read if xmlreader sees a "/" it reads a fraction
  else midi ticks for backwards compatibility
