MSBuild command line fails when Build Configuration name contains Spaces

[LK-Simon]

Where the Build Configuration name contains a space, MSBuild will interpret each distinct word as an additional parameter.

Easy solution is to wrap the name of the Build Configuration in double-quotes.

I shall implement the solution when I have time and issue another pull request for reintegration into the origin.

Once peer-reviewed and reintegrated into this origin repository, this issue can be closed.
