When using the plugin with out any explicit command options but using the "Pass build variables as properties" option I'm finding the generated command line has broken properties generated.

I get the following
Path To MSBuild.exe: C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe
Executing the command cmd.exe /C C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe /nologo /p:label=VS2012WDK;Configuration=Win8+Debug;Platform=x64 && exit %%ERRORLEVEL%% from C:\jenkins\workspace\VCHIq_Interface_Driver_(staging)\Configuration\Win8 Debug\Platform\x64\label\VS2012WDK

As you can see the /p option has no quotes and has change the space in the Configuration name into a plus.

version 1.16 work as expected.
