0.4.1

This is a bug fix release over 0.4.0:

Bug Fixes:

• #73/#80:
  Rolling an update to the day of month field could cause setting an invalid date, which will eventually return
  a None result from the next/prev methods. This case is now handled and will propagate a carry over value to
  the month field whenever it happens.

Changes:

• #81: The signature for the set method in the IsDateTime typeclass
  has been changed to capture errors when setting the values.
• #78: Upgrading the Scala version to 2.12.2 means that case classes
  do not support anymore having implicit parameter lists. This means that all node class implementations under package
  cron4s.expr have been rewritten using normal Scala classes instead of case classes. This means that they can not
  be used anymore in pattern matching and that binary compatibility in their case has been broken.

Version Upgrades:

• Scala: 2.11.11 / 2.12.2
• ScalaJS: 0.6.18
• Scala Java Time: 2.0.0-M12
