Clarify that lambda expression, 'any' and 'all', can be applied to collections of all types.

In Section 5.1.1.10 Lambda operators the sentence
"a Boolean expression that uses the lambda variable name to refer to properties of the related entities identified by the navigation path"
seems to suggest that one would only be apply our Lambda expressions against collections of entity type.
Quick check with Ralf confirmed my impression that we should be able to apply lambda expressions on collections of any and all types.
