make_mutable needs a parameter to control streaming

	return MutableDataset(self.resource)

There is quite a bit of confusion about what mutable means, what behavior it limits, etc., but one of the biggest causes for confusion is that mutable and streaming do not appear to be mutually exclusive. For that reason make_mutable should really take a parameter for streaming that will also ensure the returned MutableDataset has the desired streaming-ness.

ds.edit(streaming="no") seems to get us around this for now but an integrated solution for make_mutable would be much appreciated, as well as a FAQ/explanation about exactly what mutable and streaming, as states, are, are not and how they relate to each other.

There is a connection here that also needs to hook in for replace_from_csv, which internally needs to manage these states for the user based on whatever state it is before replace_from_csv is called. @xbito i'll take your advice about what additional ticket might be needed there.
