updated Irfanview download URL, old one was not valid anymore

as title says, currently the Irfanview package cannot be installed:

Write-Error : IrfanView did not finish successfully. Boo to the chocolatey gods!
-----------------------
[ERROR] Exception calling "GetResponse" with "0" argument(s): "The remote server returned an error: (503) Server Unavailable."
-----------------------
I changed the download URL from
http://www12.tucows.com/windows/files/iview437_setup.exe
to
http://www.tucows.com/download/windows/files/iview437_setup.exe
