2.3.0

• Fixed widget changing its size on every {cycle}/{random} tick, which kept pushing the neighboring panel widgets aside [#166].
• Fixed click handling being an item anchored inside a layout, which could put the clock off center.
• Fixed "Container fill height" pushing the clock to the top edge of the widget.
• Changed both "Container fill" options to stretch the widget itself.
• Added "Minimum width" and "Maximum width" options to set the widget width explicitly.
