Title: Ignore static fields in jsonFormat

When a case class has static fields, for example a SerialVersionUID, then you cannot use jsonFormat. Since these fields don't have to end up in the Format, these can just be ignored. This commit changes the behavior of jsonFormat to ignore static fields and then it is possible to serialize case classes with a static field.
