x11/lxqt-panel: update to 1.1.0

Main changes:
-Now the legacy tray icons are shown inside Status Notifier when the System
Tray plugin is enabled. That removes some problems of the old tray widget.
-Reset buttons are fixed in config dialogs.
-Desktop names are shown in the context menus of task buttons.
-The panel config dialog is split into 3 sections, for having a sleeker GUI.
-The clash between the main menu shortcut and the built-in shortcuts of the
search entry is fixed.
-Added options for the button label and style of Directory Menu.
-Fixed resetting of System Statistics graph on auto-hiding panels.
