Added changes for Australian Holidays

[KJ-Cox]

Modified FanartHandler.Holidays.xml to work with Australian holidays using AU.
This does require the user to add <entry name="HolidayCountry">AU</entry> to the <section name="FanartHandler"> of the FanartHandler.xml file in the "C:\ProgramData\Team MediaPortal\MediaPortal" folder.

@KJ-Cox Please add new holidays as they occur (by date), i.e. in the file there are holidays in order and at the end Daylight Savings...
