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

-SLCD Synchronous driver
-=======================
-
-An LCD display is made of several segments (pixels or complete symbols) which
-can be block light or let light through. In each segment is one electrode
-connected to the common terminal (COM pin) and one is connected to the segment
-terminal (SEG pin). When a voltage above a certain threshold level is applied
-across the liquid crystal, it will change orientation and either let light
-through or block it.
-
-The driver supports segment on/off/blink, animation and character display.
-
-Each segment has a unique int32 segment id which is used by the driver. The id is
-combined by common number(COM) and segment number(SEG), the COM and SEG start from 0.
-The unique segment id is calculated by this formula: (COM << 16) | SEG
-For example a 8(coms)*8(segments)SLCD, the unique segment id for segment should be
-
- +-----+-----+---------+
- | COM | SEG | ID |
- +-----+-----+---------+
- | 0 | 0 | 0x00000 |
- +-----+-----+---------+
- | 1 | 0 | 0x10000 |
- +-----+-----+---------+
- | 7 | 7 | 0x70007 |
- +-----+-----+---------+
-
-Segment ID can be calculated using the pre-defined macro SLCD_SEGID(com, seg).
-
-For character display, the "segment character mapping table" and "character mapping table"
-should be setup in configuration. The driver have no API to setup/change those
-mapping setting.
-There are two pre-defined "segment character mapping table" in this driver, 7 segments
-and 14 segments. The 7 segment character mapping can display 0-9 and a-f, the 14
-segments character mapping can display 0-9, A-Z and some special ASCII, for more
-details please refer to hpl_slcd_cm_7_seg_mapping.h and hpl_slcd_cm_14_seg_mapping.h.
-Application can also adjust this mapping table in the configuration header file,
-to add more character mapping or remove some unused character.
-
-The "character mapping" is used to setup each character in SLCD display screen.
-The driver supports multiple character mapping, the max number varies on different
-MCU/MPU. For example if an LCD display screen has five "7-segments character" and
-eight "14-segments character", and the MCU support max 44 characters setting, then
-the 13 character should be setup in configuration. Application can select any
-position from those 44 characters setting to save those 13 character.
-The index of character setting will be used in the driver API. For example:
-five "7-segments character" setting to 0 to 4 and eight "14-segments character" setting
-to 10 to 17. Then the application can use index from 0 to 4 to display the
-"7-segments character" and use index from 10 to 14 to display "14-segments character".
