A few improvements

Hi everyone, the update to v2.2 contains the following:

• new: autosave after each puzzle unlock, you can choose between your manual and the auto save when loading (so they are two separate savegames)

• new: 8 players per room allowed (not sure if it is stable, let me know! Take care of your toes!)

• new: first batch of Portuguese translation (thanks to Marina Herrmann)

• new: 100% leaderboard for speedrunners of room 2 (Barbara's secret), you have to solve every puzzle, the order is not important. You can check the state by pressing F1, when there is no hint left you can leave

• fixed loading with missing savegame

• fixed duplicate resolutions in settings

• fixed shadow opacity, so it won't make it impossible to read things

• fixed the hugeness of the shoe (just a little bit :D)
