MAINT refactor DictVectorizer's transform+fit_transform (1)
...
Also:
* postpone attribute setting to the end of the fit_transform algorithm,
so that exceptions leave the transformer in a consistent state;
* call sort_indices on CSR result.
Didn't refactor fit as I couldn't get the code shorter without making
_transform cumbersome to read.

ENH sort option for memory-efficient DictVectorizer
...
Added memory efficient UnsortedDictVectorizer
When loading really large files for SKLL, I found that temporarily
storing a list of dictionaries to pass to DictVectorizer was frequently
using up huge amounts of memory. You can now call `fit_transform` on an
iterable, and not have to waste the temporary space.
Sorting is done in-place, so it doesn't waste memory.
