nTaskSwitch replaces, and lets you style the alt-tab dialog. This is particularly important on Windows 8, where the old-style icons-only alt-tab dialog is otherwise used while explorer is not running as shell.
nTaskSwitch will eventually support all layout settings, but for now, Start is locked to `TopLeft`, and PrimaryDirection is locked to `Horizontal`. The prefix for the layout settings is nTaskSwitch.
