* Mod manager portrait mode
* Mod manager portrait and auto scroll
- MM switches to stacked expanders in portrait.
- Use AutoScrollPanes.
- Disable the enter/leave listener of AutoScrollPane in Pickers which disable the default ScrollPane to roll their own - helps all such pickers.
- No expander open/close persistence on purpose.
- PickerScreen a bit cleaned 'cuz I needed to understand something.
- Marked mods from the kill-list that are already installed.
- Button sync now OK when counterpart missing (deselects other column).
