New 64bit version available.

After discovering that there were two problems with the previous 64bit build, it has been rebuilt. It's now available and can be downloaded. The new build has fixed the following discrepancies...

1. Fixed - The Update icon now shows in the System Tray (and desktop notifications). This allows users to click the icon in the system tray in order to install updates.
2. Fixed - Nitrogen (Wallpaper Changer) now has the default "Zoomed Fill" setting in order to fit the wallpaper onto all monitors. This is the default setting and can be changed to your preference.
