Use patch instead of full update.

Partially reverts changes of 9d0255e7.
Added helper methods to Room which transform the ContentGroup collection
from Set to Map. Content IDs are now removed from groups when Contents
are deleted.

Replaced the following events with StateChangeEvent:
* FeatureChangeEvent
* LockFeedbackEvent
* LockQuestionEvent
* LockVoteEvent
* LockVotesEvent
* PiRoundCancelEvent
* PiRoundDelayedStartEvent
* PiRoundEndEvent
* PiRoundResetEvent
* StatusRoomEvent
* UnlockQuestionEvent
* UnlockVoteEvent

Removed the following redundant events:
* DeleteAllLectureAnswersEvent
* DeleteAllPrepareationAnswersEvent
* DeleteAllQuestionsAnswersEvent
* DeleteAllQuestionsEvent
* LockQuestionsEvent
* UnlockQuestionsEvent
* UnlockVotesEvent

To trigger events, some code was migrated to use EntityServices instead
of directly accessing Repositories.

The hook methed was never called.

The event is now published for every single patched entity.

`modifyRetrieved` can be overriden to modify Entities before they are
returned by CRUD methods.

Mock the correct method.

Implements #30.
Fixes #29.

Patching of child objects is now handled.

This was broken by refactoring of events.

a visitor interface.

* Avoid use of obsolete v2 classes in service and repository layers
* Optimize imports

The format for answers is now set based on the content's format.
