wpa_gui: Themed icon loader

Browse Source 
Signal strength meter uses non-standard icons (not included in the
freedesktop icon specification), which might not be available in all
icon sets on the market. What's more, according to the latest Ubuntu
practices, in the status-like places one should use symbolic icons.
Unfortunately not all icon sets provide them.

In order to overcome this inconsistency, we are going to try to load
more than one icon from the current theme in the fallback-like
fashion.
