Overriding title in "Content Item" widget doesn't work for "Featured" view mode of Content Pages

Here is a patch that fixes the "Featured" view mode, but actually breaks the "Full content" view mode. I have a @todo in the code about how to fix that! This is also going to need new tests to check both those view modes and make sure everything is working as it should (and so I don't break this again).

Here is an updated patch that works with all view modes, on both panelized and un-panelized content types. Plus a patch to panopoly_test to actually test that that is true. :-)

Noticed this stray '#' when skimming through the last patch. Here's a new one to fix it!

Er, it helps if I actually attach the patch. :-)

Trying the two latest patches on Travis-CI:

Here is a new version of this patch which works when a Panelizer view mode includes a "Node content" Pane that renders the node in a different view mode. I'll test this one on Travis-CI too in a moment..

EDIT: Travis-CI build for latest patch: https://travis-ci.org/dsnopek/panopoly/builds/50373108

Here are some re-rolled patches now that some other things have gotten merged.

Looking good on Travis-CI! Committing.
