added a whole slew of features

- added configurable hourly forecasts
- battery indicator moved to inside "colon" between hrs and min
- included gbitmap_tools lib to resize bitmaps
- moved back to single images for better memory optimization
- added extended weather info (on double shake), to show sunset, sunrise, windspeed, humidty, high and low for the current day

if you think this takes away from your watchface I am happy to keep maintaining this and release it as different one.
