Fixed a lot of bad match bugs in qtdragon_hd. I can't use pull request yet and it's traditional for now. I have modified the latest qtdragon_hd.ui file. so it is possible that it is enough to replace the whole file if you accept these changes.
qtdragon is now working properly, ngcgui is starting (I don't know what's going on yet, but it's a detail), the buttons that are supposed to turn off during work also work fine. Thanks.
