Better error message with transclude / ng-transclude

[rngadam]

Based on this transclude example: http://jsfiddle.net/ospatil/A969Z/

If we remove transclude: true from the directive (imagine that the programmer has forgotten it), this is the error message generated:

TypeError: undefined is not a function

Suggest a better error message here:

ng-transclude directive called but no content to be transcluded - have you forgotten to set transclude: true?
