Support SkipField in to_representation

Browse Source 
Allow a broader usage of the `SkipField` exception within Serializers, making it possible to skip a field from being included when `to_representation` is called on the field level. Previously this has already been supported for `Field.get_attribute`, but not `Field.to_representation`.

For an example, this change allows raising a `SkipField` exception in a function called by `SerializerMethodField` in order to omit that field conditionally.
