Issue #1235 - Add icon for ABP in the Windows control panel

   Compilation Note:
   You may see linking errors that look like these:
     <quote>LGHT0217 : Error executing ICE action 'ICExx' [...] The error code is 2738.</quote>
   The documentation for this error code talks about custom actions,
     even though the CustomAction keyword does not appear in this source.
   Certain WiX elements are implemented by MSI custom actions,
     which means this source implicitly declares some insofar as the Windows Installer sees it.
   These errors are benign and can be avoided by some fiddling with the registry on the development machine.

       Define and schedule a "Custom Action Type 1" to ensure that IE is closed before installation.
       Because WiX is closely tied to the MSI database format, there are multiple tags required to do this.
       The "CustomAction" tag defines the tag itself, but doesn't sequence it;
         it defines an entry in the "CustomAction" table.
       The "Binary" tag describe an asset that's incorporated into the MSI but that is not an installed component.
       The "Custom" tag defines when the action executes by defining an entry in one of the sequence tables.
       
       Attribute "Return" sets the "Custom Action Return Processing Options" to zero,
