Selfie mode + small fixes

- The secondary message when picking up a piece of clothing is now as it should be.
- The post-processing effects are now activated correctly when starting a level.
- The missile spin when returning to its initial position is slower.
- Added Chinese pixel font in some areas where it wasn't applied (cinematics, initial menu joke).

- The HUD of the tutorial about launching missile is removed once you have broken the target.
- Selfie mode in photo mode.
