Enhancement suggestion: ListGridField.setDefaultProperties()

Hi Isomorphic,

I noticed that there is no ListGridField.setDefaultProperties() - most likely because ListGridField does not inherit from Canvas. But as every Canvas-child has its own Abc.setDefaultProperties(Abc instance), perhaps you can add this for ListGridField as well. Currently I'm using subclasses here in order to safe lines of code.

Best regards
