BUG: fix reading pre-0.14.1 pickles of containers with one block and dup items
Series, frames and panels that contain only one block can be unpickled
under the assumption that block items correspond to manager items 1-to-1
(as pointed out in #7329).

I still don't have any of darwin/win/32bit platforms at hand, so I
cannot post those pickles.  Also, my linux has a fresher python than
indicated by filenames of existing pickle test data.  I did generate
some data to test the fix, the question is do you want me to upload it?

just put up some legacy files whatever your python / platform (if u want to multiple versions of oython that's ok)

it doesn't matter much that we have for every platform for very version

cross compat is pretty much there
 Ok, I've added pickles for 0.13.0, 0.14.0 (just in case) and 0.14.1.
 perfect! ping when green
 you have to add the directory of 0.14.0 to `setup.py`, see here: https://github.com/pydata/pandas/blob/master/setup.py#L578

(actually prob is a better way to do by adding all directories under data), any idea?
 @immerrr pls rebase another commit added the 0.14.0 pickle dir already
 rebased and green
 @immerrr thanks for the fix! preserving pickle compat is never easy!
