MSBuild compability

When automating some C# deployment on Windows, be aware that there is two MSBuild instances available.

After some random error, I found msbuild has two similar versions. The continuous integration server was pointing to:

	C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe

This was firing a build that was impossible to reproduce in my computer, not even on the build server… until I realized the path was strange.

It end up that the msbuild that the Developer Command for VS2013 uses this msbuild:

C:\Program Files (x86)\MSBuild\12.0\Bin\MSBuild.exe

This version supports some extra features like /T:Package.
