Merge pull request #3 from ron064/watchface

[Thanks Ron!]  Reduce Memory.
 - Persnickity formatting tweaks (spacing, tabs, braces)
 - Cleanup of 'stale' commented out code (it's version control, it's not lost!)
 - Technically correct, the best kind of correct. (isn't a GFont)
 - Extended the concept to custom fonts (though some of these are handled later in set_unifont anyway).
 - Tweak 999 (@start) to show as N/A in the most RAM-savvy way possible
2.3.3 version, minor TZ/JS tweaks
