XTest plugin integration (milestone2)

[Manuel Breugelmans]

As planned I've visually integrated the QxRunner lib as a plugin. For a 
screenshot check out -> http://mbreugel.blogspot.com/. Can run it for 
yourself by de-commenting add_subdirectory(xtest) in 
kdevelop/plugins/CMakeLists.txt. I wont keep spamming this ML with evry small  
milestone completion though, so look at the blog if you'r interested :)

Next is support for QTest, at first without advanced test discovery, by simply 
registering the tests through an xml file or so. Unfortunatly the academic 
year is ending and thats robbing me of my free time (task deadlines + exams 
closing in at lightning speed).
