Fix startup segfault crash
Review Request #120721 - Created Oct. 22, 2014 and submitted - Latest diff uploaded
Initially the app used to crash when started, and returned segmentation fault. In the KHangman class the show() function of KXmGuiWindow is overriden, which now checks for the kvtml files first. If no files are found, a QMessageBox is displayed, otherwise the mainwindow is loaded.
