Subject: [PATCH] Catch JsonParseException in block entity names

As a result, data that no longer parses correctly will not crash the server
instead just logging the exception and continuing (and in most cases should
fix the data)

Player data is fixed pretty much immediately but some block data (like
Shulkers) may need to be changed in order for it to re-save properly

No more crashing though.
