Improve syntax highlighting (syntaxes/cml.tmLanguage.json)

[stefan-ka]

I implemented a first version of the syntaxes/cml.tmLanguage.json file for the syntax highlighting. However, we should improve this a bit later:

• Match keywords locally (especially tactic DDD stuff)
  • everything is matched globally now
• Match and highlight IDs (of Bounded Context, Aggregates, Entities, and so on...)
