Fixed problems causing tray icon not to appear in KDE:

I found a bug that prevents the tray icon from being shown in KDE. One part of it is clearly a typo (wl00.png doesn't exist), but the other part *might* be needed to fix problems in XFCE. In KDE, `geometry().left()` and `.top()` return 0 when everything is working normally. I think this is the correct behavior, so the check should be `>=` and not `=`. If this breaks XFCE, perhaps another workaround can be devised?

My Vim settings replaced the tabs in this section of code with spaces. I kept this because the rest of the file appears to use spaces. For the record, there are a bunch of buggy DOS line endings in the file.
