A FailedDisplay instance represents a Display class we tried and failed to instantiate.
FailedDisplay stores the class id which it was supposed to be, and an error message describing the failure.
The load() and save() functions work together to ensure that loaded configuration data is saved out again without modification. This ensures that running rviz with a missing plugin library won't damage config files which refer to it.
