logic: code controller

- Renamed MessageActivateTokenLocation to MessageActivateToken, since it uses the Token id (not the TokenLocation id).
- Implemented CodeController to add one snippet for each location where the activated token occurred.
- Added Semaphore to QtThreadedFunctor to prevent an evil race-condition.
- CodeView dispatches message when a token is clicked.
