Link generated Code and Definition

Simple Option: Make Links in Generated Java Files Clickable

Things like @declaredat /home/jm/work/git/jastadd/ragconnect/relast-preprocessor/src/main/jastadd/backend/AbstractGrammar.jadd:183

Preferred: Annotators

Create an annotator for things with a declaredAt doc-comment and another annotator at the declaration. Clicking them jumps between the two.
