Remove the no longer needed "file in use on sign" workaround from Setup.iss now that ISPP.dll and ISCmplr.dll are presigned (=use signcheck instead of signonce). Also remove it for islzma.dll since it was already presigned. Presign ISCC.exe as well to so the workaround can be removed all together. Simplies both Setup.iss and the setup-sign.bat which needs to be created.
