fix asl display message bug where message window wouldnt close

[tevyecowan]

• added asl app icon to desktop
• cleaned up asl start window, now displays name of user that has messaged you (if any)
• asl message windows wouldn't close if you pressed the "next" message button, but worked if only 1 message existed OR if multiple existed but you only pressed "prev". fixed bug so now you can close message windows no matter what button u press :)
