Add Icon for Custom Control / Composite Control

When a custom control is placed on the toolbox, if it is a professionally made control, it usually has a really nice icon associated with it instead of the default ("paper-looking") icon that Visual Studio inserts when no icon is available.  When you build your own custom control, you can add an icon for the control and embed it in your component's DLL assembly so that it is shown on the toolbox whenever someone adds your control.
