[Fix] Improve Class-Subclass Linkage (#1846)

* Initial thoughts

* .

* Fixed linting

* Continue work on updating identifier

* Change to uuid approach

* Localization and minor fix

* Fixed CompendiumBrowser Class filter for Subclass view

* Fixed the class name display in the subclass view

* Improved missing class visual for subclass

* Fixed character creation

* Rerender class sheets when subclass link is changed

* Use compendium source over actual uuid in search
