Output generated codec source to files

- Added SourceCodeGenerator helper class that holds the generated
  field/method source code until outputGeneratedSource is called to
  generate the source for the entire class and output to a file
  under generated-sources.

- Modified TransformerGenerator and JavassistUtils to use the
  SourceCodeGenerator.

- Other pom changes to eliminate Eclipse errors.
