dfm_gen & merger: Changed word cutoff point to be a general setting in dfm_gen. Cuts off at the last [.?!] before the cutoff point (so returns documents at a sentence, shorter than cutoff).

bulk_writer: setting names(x) <- NULL when there is only one value (list or otherwise) to be updated.
...
This is because R apply treats rows of single values as a matrix, while it treats rows containing lists as (named) list. This has the nasty result of getting subvalues when using to JSON. i.e. computerCodes.actors = [list, of, ids] becomes computerCodes.actors.ids = [list, of, ids].
