Patch 1.0.0.1

This is first little patch containing general bug fixes. Changelog: [list] [*] Fixed: A bug where the sandbox- and profile editor would not set up correctly. [*] Fixed: A bug which would sometimes show the save-prompt before starting a festival even if the festival was saved already. [*] Fixed: The operating plan timeline would not show the correct time, this is now fixed. [*] Optimized: Improved the entrance requirement so that live mode can only be started once all visitor types can enter the festival. [/list] If you want to get updates even sooner, check out the public-test branch! Let me know if you have any issues! Thanks! Johannes
