[FLINK-2096] Remove implicit conversion from Window Stream to Stream
This causes unexpected behaviour, for example in:
ds.window(...).map(..)
The user would expect some kind of windowing to take place. The
windowing, however, cancels out with the implicitly inserted flatten()
call.

> Project: Flink
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 0.9
> Reporter: Aljoscha Krettek
>
> At least one user ran into a problem with this:
> http://stackoverflow.com/questions/30461809/in-flink-stream-windowing-does-not-seem-to-work
> Also, the implicit conversions from Java DataStreams to Scala Streams could
> be problematic. I think we should at least make them private to the flink
> package.
