Removed the delete permission from the administrator group (only super admin has it).
Added (unused) functionality for CAModel dictify() to output dates as strings or Date objects.
Updated the method-method-schema relationship to 1-n rather than 1-1, which meant that schemas couldn't be reused.
Updated method_schema_parents_item.pt to hardcode the method name as the template system isn't flexible enough for its requirements.
Updated method_schema_parents_mapping.pt to correctly show preview fields for parents that were added on load rather than through the add sequence.
Updated the footer to use the ANDS specified text.
updated workflows.py->_render_model to display untouched pages better (it now attempts to display without validation, then tries with validation and if it fails to validate it will show the form as failing validation).
