Refactorings/Clean-Up

• static variables in configuration aspect should be normal terminals of ragconnect nonterminal
  • and they should not be set inside Compiler.parseProgram but either outside of it or in a separate method with a more appropriate name
• move some of the lookup methods from analysis aspect into name-resolution aspect
• prefix all aspects with "RagConnect" to enable easier refinement for this and other preprocessors
• move TestUtils so separate package, e.g., utils
  • extract inner classes and put them into new package as new files
• move mappings into template where possible
• rename "forwardingNTA" to "forwarding" (since no NTAs are used anymore)
• add reset to evaluation counter

  public void {{parentTypeName}}.ragconnectResetEvaluationCounter() {
    _ragconnect_evaluationCounter.reset();
  }
  class EvaluationCounter {
    public void reset() {
      counters = new java.util.HashMap<>();
    }
  }

• remove any remaining @Tag("New") from tests
• rename ci job pages-master back to pages
• rename endpoint to port
