--------

* use plone.app.contentmenu.interfaces.IDisplayViewsMenu instead of plone_displayviews
for menu declaration since it doesn't work with plone.app.contentmenu > 2.0b3
and zope.browsermenu installed.

--------

- import Batch directly from PloneBatch since with Zope 2.13 Batch is not
available at the package level when plonetruegallery is loaded.

--------

* made the basic gallery not store it's cached images since it would never be able to really
cache them anyways. This fixes the zodb potentially growing forever on sites that use the
gallery portlet since it needed to calculate the gallery on every new image request, which
would cause a new write to the database. FYI, packing the database brings it back down to
it's normal size.
