Adding optional support for plone.app.contentlisting/search
Update .travis.yml

Try to stay within timelimit
Fix several FlareContentListingObject methods
Fix FlareContentListingObject.EffectiveDate()

The DateTime returned in `effective` can't be strftime()d if it's year
is <1900. Archetypes returns a fallback date (FLOOR_DATE) for
`.effective()` with the year set to 1000 if effectiveDate is not
set/None. `.EffectiveDate()` instead returns 'None', so we use that.
Mention ContentListing support in CHANGES
Update README.rst

used to say just Plone 4.1 so changed to "Plone 4.1 (or later)"
undo patch to return also solr-indexes which breaks stuff. remove unused imports
Handle Int Values that are actually None

Thank you so much unordered.py for claiming to implement
IOrderedContainer but then just return None as position information.
Nobody would be able to query for an adapter to check if a folder
actually implements IOrderedContainer.
Try to get reordering to work again
