function panopoly_images_field_widget_form_alter in Panopoly 7

Implementation of hook_field_widget_form_alter().

This a minor hack to improve compatiblity with sites that use the the focal_point module, by disabling focal_point on fields that have manualcrop enabled. If users want to use focal_point, they simply have to disable manualcrop for that field.
