Title: MRG: deterministic vocabulary_ for DictVectorizer

@larsmans I changed the default behavior of the `DictVectorizer` class to make sure that it generates a deterministic vocabulary. The old & faster behavior is still possible with `sort_feature=False`.

Also I rewrote a bit the narrative documentation to make it more noob-friendly.
