javaInterfaces extension property is ignored for Enum types

[Ghorric]

It is not possible to add an Interface to an Enum:

{
    "type" : "string",
    "javaInterfaces" : ["MyInterface"],
    "enum" : ["FOO", "BAR"] 
}

org.jsonschema2pojo.rules.ObjectRule has the 'addInterfaces' method that is missing in org.jsonschema2pojo.rules.EnumRule:

    private void addInterfaces(JDefinedClass jclass, JsonNode javaInterfaces) {
        for (JsonNode i : javaInterfaces) {
            jclass._implements(jclass.owner().ref(i.asText()));
        }
    }

@Ghorric We can definitely fix this. Do you actually have a need to support this or is this simply something you have found whilst experimenting?

[Ghorric]

This is actually something that I need. There is no workaround for this problem because you can't extend an Enum :(. A fix for this issue would be much appreciated.
