PSES side changes for issue #96 - support x86/x64 debugging.

Besides **all** the awesome work @adamdriscoll did to enable this; there are some changes that need to be made to package.json in the vscode repo.  In order to support those changes, we need a different filename for the x86 batch file that launches the x86 debug host.
