Implemented icon theme option.

Changes in this commit include:
 * The option itself;
 * A method of updating the option right after Apply or Ok is pressed
   in the settings dialog;
 * A new WeatherIconPrivate class to store the methods previously
   in WeatherIcons, as well as the settings;
 * Improved icon name helper function in METAR parser;
 * A few cleanups to the WeatherIcon class.
