All tests are skipped if they are run from a file system path that contains spaces

[brobert83]

When running the tests with the maven plugin from a path that contains a space, an internal error is created which causes all tests to be skipped.

I have debugged it and traced the problem in net.thucydides.core.reports.xml.XMLTestOutcomeReporter in the generateReportFor method.

Not sure how to fix though, didn't had time to investigate too much.
