Some types that have registries support existing without being in a registry and therefore have no key. This is part one of supporting that, adding a Registry#getKey(Object) method to be able to get the key for an object so we can remove Keyed from such objects. This also deprecates Keyed#getKey on TrimMaterial and TrimPattern as these are the 2 offending types currently in the api.

Subject: [PATCH] Improve Registry
|
|
|
|
Adds Registry#getKey(Object) which should be the
|
|
primary way people get the key for an object. Registry
|
|
items need to exist without having a key and so
|
|
getKey() methods on Keyed objects that have a registry
|
|
are marked as Deprecated or Obsolete.
