VC7.1: sln vs. vcproj

[Peter Schregle]

Thanks.

We changed from sln to vcproj, because we've had problems with the solution files in SourceSafe, so we decided to have only the vcproj in SourceSafe.

Thus, whenever the whole stuff (a few hundred projects) is moved to another machine, we wanted to avoid the necessity to load every project at least once into the IDE to be able to build with Visual Build.
