Fix Scaladoc deprecation note in MustMatchers
Bumped ScalaTest version to 2.0.1-SNAP4.
Merge branch 'JIRA-288' of https://github.com/gcberger/scalatest
Upgrade to Scala 2.11.0-M7
Upgrade to Scalacheck 1.11.1

See the TODO-maxDiscarded markers to complete the migration.
Scalacheck now specifies a ratio rather than an absolute number
of discarded tests.
