lib group storage rework (#162)

saving decks that use lib groups will no longer save the whole file path to that library (at the expense of the structure needing to be the same)

also some ui/ux improvements:
- more menus in sidebar remember their collapsed state between deck/node switches
- adding a lib group will name the group node appropriately
- save dialog properly remembers the most recent path when invoked via ctrl+s and the deck hasn't been saved before
