SPECS2-4.2.0

Upgrade version

Upgrades

• scalacheck upgraded to ScalaCheck 1.14.0. It is now possible to visualize the seed used
  to generate a counter-example and reuse it to run a property (myProp.setSeed("xxx") or use scalacheck.seed xxx on the command line)

Improvements

• Use foldLeft instead of /: (#654) (thanks to @xuwei-k)

Fixes

• junit fixed an issue where List(1,2) must contain(===(2)) would fail with JUnitMatchers and a JUnit test class
