Change exception when MSBuild returns a non-zero exit code to MojoFailureException.
Fix issue whereby externally defined values for cxxtest.home and cppCheck.path were not being pulled into the configuration classes. This appears to be a bug in Maven where the property expansion does not work for child tags/classes. Workaround this by creating dummy configuration parameters at the top level that capture the external values and fix up the configuration before real Mojo execution begins.
