Missing dependency - plone.app.contenttypes

[djowett]

Shouldn't this be a dependency in setup.py? Without it I get an error on vanilla Plone 4.3.11

 ImportError: No module named contenttypes.behaviors.leadimage

[djowett]

Or (perhaps more likely) this product should cope with leadimage behavior being absent

[rnixx]

Yes leadimage should be optional. A view uses it if available, thus this can be solved like so:

from zope.interface import Interface
try:
    from plone.app.contenttypes.behaviors.leadimage import ILeadImage
except ImportError:
    class ILeadImage(Interface):
        """Dummy lead image interface if plone.app.contenttypes missing"""

feel free to open a PR :)
