Missing support for String and Object arrays

[anotender]

Application fails when in encounters String[] or Object[] while building schema. It is missing in the scalarsRegistry in the JavaScalars class and the library tries to register it but it fails because of regexp check failure. The solution that works for our case is to add following entries to the scalarsRegistry:

scalarsRegistry.put(String[].class, new GraphQLScalarType("StringArray", "StringArray type", new GraphQLObjectCoercing()));
scalarsRegistry.put(Object[].class, new GraphQLScalarType("ObjectArray", "ObjectArray type", new GraphQLObjectCoercing()));

@anotender Do you think it would make sense to support direct mapping of Java arrays into GraphQL lists type wrapper, i. e. String[] > [String]?

@igdianov for the readability of the schema it looks like it is a good idea. In my opinion it could be implemented this way.
