Sensor Watch Simulator (#35)

* Put something on screen * Use the 32bit watch_date_time repr to pass from JS * Implement periodic callbacks * Clear display on enabling * Hook up watch_set_led_color() to SVG (green-only) * Make debug output full-width * Remove default Emscripten canvas * Implement sleep and button clicks * Fix time zone conversion bug in beats-time app * Clean up warnings * Fix pin levels * Set time zone to browser value (if available) * Add basic backup data saving * Silence format specifier warnings in both targets * Remove unnecessary, copied files * Use RTC pointer to clear callbacks (if available) * Use preprocessor define to avoid hardcoding MOVEMENT_NUM_FACES * Change each face to const preprocessor definition * Remove Intl.DateTimeFormat usage * Update shell.html title, header * Add touch start/end event handlers on SVG buttons * Update shell.html * Update folder structure (shared, simulator, hardware under watch-library) * Tease out shared components from watch_slcd * Clean up simulator watch_slcd.c inline JS calls * Fix missing newlines at end of file * Add simulator warnings (except format, unused-paremter) * Implement remaining watch_rtc functions * Fix button bug on mouse down then drag out * Implement remaining watch_slcd functions * Link keyboard events to buttons (for keys A, L, M) * Rewrite event handling (mouse, touch, keyboard) in C * Set explicit text UTF-8 charset in shell.html * Address PR comments * Remove unused directories from include paths

 To create a new watch face, you should create a new C header and source file in the watch-faces folder (i.e. for a watch face that displays moon phases: `moon_phase_face.h`, `moon_phase_face.c`), and implement these functions with your own unique prefix (i.e. `moon_phase_face_setup`). Then declare your watch face in your header file as follows:

 ```c
-static const watch_face_t moon_phase_face = {
-    moon_phase_face_setup,
-    moon_phase_face_activate,
