at least data.table can read from a string. this should be much faster.

whether this is done or not (mem or temp.file) should be an option.
maybe readARFF(tmp.file = NULL) should mean: preproc into mem

implemented, but buggy. I will remove it from the unit tests now

this was a stupid idea, datatable writes the string always to disk :(
