Changeset 6940 for code

Message:

Resolved issue with the Questsystem causing a segfault when a level with Quests was loaded twice. The issue still persists, but not with the Questsystem anymore and it will be addressed with my next commit.
Also removed restrictions to the number of characters a quest/hint identifier must have.
