LXQt Rolling

@ben79 I ran LXQt Build # 1280 as a live desktop, did not actually install to a virtual machine.

lxqt-panel was mostly black, I suspected that a default theme was not chosen when the image was being built and that appears to have been the case. Once I selected a theme (System), then the panel appeared as it should. The issue previously reported, which you filed a bug report on, with the panel not displaying any minimized windows, is also present in this build.
