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

-The Flash Driver
-================
-
-Flash is a re-programmable memory that retains program and data
-storage even with power off.
-
-User can write or read several bytes from any valid address in a flash.
-
-As to the erase/lock/unlock command, the input parameter of address should
-be a bytes address aligned with the page start, otherwise, the command will fail
-to be executed. At the meantime, the number of pages that can be locked or unlocked
-at once depends on region size of the flash. User can get the real number
-from the function return value which could be different for the different devices.
-
-Features
---------
-
-* Initialization/de-initialization
-* Writing/Reading bytes
-* Locking/Unlocking/Erasing pages
-* Notifications about errors or being ready for a new command
-
-Applications
-------------
-
-* Mini disk which can retain program and data storage
-* Boot loader
-* Non volatile storage
-
-Dependencies
-------------
-
-The peripheral which controls a re-programmable flash memory.

-
-Limitations
------------
-
-User should pay attention to set a proper stack size in their application,
-since the driver manages a temporary buffer in stack to cache unchanged data
-when calling flash write and erase function.
-Due to flash memory architecture of SAMD21/D20/L21/L22/C20/C21/D09/D10/D11/R21,
-write operation erazes row content before each write.
-
-Known issues and workarounds
