Update to the model to fix a unit test in admin
Increment version number.  Although an ambra webapp is not going out with tonight's release, I am incrementing this as though it is, so that we can speak of "release 2.7.8" with some sanity.
Merge branch 'master' into dev-fix-unit-tests
Merge branch 'dev-fix-unit-tests' into dev/plosone-homepage
