For example, the first audio link in "The United States" English Wikipedia article - "The Star-Spangled Banner" - ends with ".oga". Without this commit the audio link is not recognized by GoldenDict: * it is not pronounced when a Preferences=>Audio=>"Auto-pronounce..." option is enabled; * clicking on the link opens it in the default browser instead of playing inside GoldenDict.
