Throw NotAllowedException for be ===
Restore a test in TestCanceledExceptionSpec
Merge branch 'fail-deprecated-be-tripleequals' of https://github.com/gcberger/scalatest into 2.2.x
Changed error message given for be === syntax.
Merge branch '2.2.x' of https://github.com/scalatest/scalatest
Bringing in George's branch that expires the deprecation period for
the be === syntax by throwing NotAllowedException, because otherwise
old code that didn't get changed already could compile but just not work.
