Title: Pickle rebased

pickle works and has save load methods

tested for models outside of tsa

ARMA needs https://github.com/statsmodels/statsmodels/commit/eaaf4e444cc2468f83652a7732360ab6efd4dcba

or equivalent

also remove_data doesn't remove _data dates and rowlabels in ARMA

--------
I think we can merge this
add the changeset for ARMA from the statsmodels/pickle branch
add then add tests for tsa

(I didn't look at VAR and AR yet, need to find an example script)
