* Update sailing_face.c
Modified sailing_face.
Added features, some of which @niclashoyer already suggested in his initial PR:
- stopwatch-like counter after start signal
- lap counter after start signal
- optional additional sounds at every minute, 30s, 10s countdown
- sound options (no sound, start only, signals only, all)
- maximum starting time up to 10min (instead of 9)
- improved timing, display is no longer delayed by sound

watch faces that handle EVENT_LIGHT_BUTTON_UP but not EVENT_LIGHT_BUTTON_DOWN
probably don't want the default EVENT_LIGHT_BUTTON_DOWN LED activation behavior
