[FLINK-5375] [doc] Fix Watermark Semantics Fix watermark semantics in documenation to be correctly aligned with implementation: a Watermark _t_ declares that event time has reached time _t_ in that stream, meaning that there should be no more elements from the stream with a timestamp **t' <= t** (i.e. events with timestamps older or equal to the watermark). Also proof-read and corrected some mistakes in event-time / watermark related docs.
