Move display of LogEntry details from the `logentry_display` and
`logentry_object_link` signals to a class hierarchy based approach.
For each action_type, an instance of a subclass of `LogEntryType`
is registered in the `log_entry_types` registry.
Analogous to EventPluginSignal, this registry is an `EventPluginRegistry`,
so it keeps track of the plugin the LogEntryType is defined in.
