Change getCode method without arguments in CodeBlock into derived attribute

[GoogleCodeExporter]

The method getCode() (see code snippet below) in CodeBlock can be refactored 
into a derived attribute.

  public String getCode()
  {
    return !codes.containsKey(languageUsed) ? "".equals(languageUsed) ? null : codes.get("") : codes.get(languageUsed);
  }

Note that fixing this issue was attempted under issue 509, but there was a 
problem with inheritance when the change was made which caused the CodeBlock 
class and all of its subclasses to become abstract.
