In some installations of XLL+ version 7 for Visual Studio 2013, the following 
					problem is occurring.
				When an add-in function is inserted or updated using the XLL+ developer tools, 
					including the Function Wizard and the XLL AddIns ToolWindow, any header files 
					that are required by the function's extensions are being inserted at the top of 
					the C++ (.cpp) source file.
				This patch addresses this problem.
