GOTTA DO

- Online help (good content while we are at it)
- Search for a city from the applet (no need to open a browser)
- Tooltip with the forecast text (like the GNOME Weather applet does).
  For this you'd have to parse the string out of the weather channel page
  or maybe let the user type in something (i.e. "Regina's Weather",
  "Grandma's Weather")
- Cleanup tmp file. 
- refresh_image() declares img_url as a char array and fetch_forecast_image()
  fills it. Both functions expect it to be a max size of 255. If it's ever
  bigger than this you'll have a problem, so it would be best to make this
  more dynamic.  

MAYBE

- Swith between forecast and current weather
- User selectable color for the background
- Show temperature forecast (user selectable)
- Get rid of WGET and use ghttp
- Show next days forecasts in the applet (user selectable)
