Validation to produce XML output

[Former user]

Original [issue 264](https://code.google.com/p/okapi/issues/detail?id=264) created by @ysavourel on 2012-08-07T00:23:06.000Z:

The current outputs of QualityCheckSession.generateReport are html and tab-separated values. Tab separated values is a problem if the segments have line breaks, and the html is hard to parse. So it might be nice if we would also generates an XML report.
