Languages used in the DSL is now a LanguageFunction which supports both Expression/Predicate, which allows it to be used as intended in the Camel routes.

> The camel-scala DSL crates Expression for languages used in the DSL, regardless if they are to be used as Prediacates.
> The Java DSL is capable of creating a Predicate instead. For example in a Content Based Router, InterceptFrom -> When etc.
> We ought to look into being able to supply Predicate when a predicate is really to be used.
> See ScalaPredicate
> This affects for example the improved simple language which operates different accordingly to whether its a predicate or expression being evaluated. So in camel-scala this mode will always be Expression, despite a Predicate was to be used.
