[All] Code refactoring

- keys beep and haptic refactoring (not anymore audio events)
- trims move/mid/min/max refactoring (trim end splitted to trim min / trim max)
- S6R new alarms
- S6R servos/rx status displayed as a text (not an integer which has no sense)
- Timer countdown configuration
- The splash was not displayed (but the timeout was there) after the first calibration
