Add Lambda Operator all

[TrevorPilley]

To be implemented in feature-lambdas

The all operator applies a Boolean expression to each member of a collection and returns true if the expression is true for all members of the collection, otherwise it returns false.

Example: all Orders that have only Items with a Quantity greater than 100

http://host/service/Orders?$filter=Items/all(d:d/Quantity gt 100)
