Bug in ETSLayoutMgr::DeleteReg()

[Coruscant]

ETSLayoutMgr::DeleteReg() doesn't actually work as advertised as it does not delete or overwrite the registry value (tested: Windows 10) A implementation that works would be:

HKEY hSectionKey = AfxGetApp()->GetSectionKey(lpszSection);
if (hSectionKey)
{
	auto err = RegDeleteValue(hSectionKey, lpszKey);
	RegCloseKey(hSectionKey);
	return (err == ERROR\_SUCCESS);
}

return false;

NOTE: Not regression tested on older versions of Windows.
