Rename ResultOfMessageApplication to ResultOfMessageWordApplication; added test and implementation
for (of [...]) syntax for message in have.
Move the length/size/message -> HavePropertyMatcher tests where they belong,
in org.scalatest's ShouldHavePropertiesSpec. Added tests for have not.
Fixed failed tests in InspectorShorthandsSpec.scala.
Changed 'contain only' matcher behavior so that LHS must have all of elements mentioned in the RHS.
Removed commentted tests in InspectorShorthandsSpec.scala, which are map and order related, no longer relevant.
