Make just opening the generated MSVC solution file not modify it

The format of the generated MSVC solution file is fixed in a way that
just opening it in Visual Studio and immediately closing it again
without performing any modifications does not trigger a prompt to save
the solution file. This behavior was caused by several minor
incompatibilities between the generated file and what Visual Studio
2008 expected, so Visual Studio transparently fixed the file format,
marking it internally as modified.
