Support complex generic type response mapping procesing

Beginne mit dem in Parser.kt und MappingParser.targetType gemeldeten Mapping-Parser und untersuche anschließend MappingConverter.kt und MappingErrorListener.kt. Reproduziere das dokumentierte Mapping für Map<String, List> und verfolge den Parserfehler. Erledigt ist es, wenn das verschachtelte generische Mapping ohne den gemeldeten Verarbeitungsfehler erfolgreich geparst wird.

Hi @hauner!

Processing response mapping of generic types with depth 1 works fine:

FooToBar => java.util.Map<java.lang.String, java.lang.String>
FooToBar => java.util.Map<java.lang.String,  java.lang.List>

But it doesn't work with a complex generic types such as:

FooToBar => java.util.Map<java.lang.String, java.lang.List<java.lang.String>>

The output of processing:

line 1:64 no viable alternative at input 'java.util.Map<java.lang.String,java.lang.List<'
processing failed!

It would be useful to add complex generic types support.
