* Animations can now display a label indicating the percent being shown. The
    forecast window uses this extensively.
  * All URIs can now be changed via command line/config file options.
  * Added ./configure checks for b0rken snprintf/vsnprintf.
  * Added ETA forecasts. These are mixed in with the AVN forecasts in the
    rotation, sorted by time.
  * Added display of the forecast type, which shows up at the bottom of the
    forecast window where wind chill, heat index, and so on appear.
  * When not animating, the percent chance cutoff can be adjusted using the
    mouse wheel (as mapped to buttons 4 and 5).
  * Made all forecast and warning options optional. Thus, if you don't specify
    e.g. avn-station, no AVN forecasts will be downloaded.
  * Regularized options: -radar is now -radar-uri, and -zone is now
    -warning-zone.
  * Support for POST for the radar image.
  * Support for system-wide configs.
  * -email is now optional too.
  * Lots of code cleanups.
