Fix T91054: Editing group custom property gives error
This commit fixes the custom property edit operator for the the case of editing group properties. Currently this isn't supported very well, the data is converted to a string, but the operator shouldn't fail anyway. This allows editing properties created like this: C.object['abuse'] = {'parent' : ['child1', 'child2']} These changes reflect some issues with the design of the operator. Requiring guessing the type of the data does not work well at all, and makes code more complicated. In the future this operator can be updated to use a type drop-down.
