Feature/sidebar hotkeys

[Xemptuous]

• feat: added 2 new hotkeys to quickly collapse file tree cursor is inside:
  • o - similar to CR but also folds parent if over an item with no collapsibility
  • O - close fold up to direct parent regardless of collapsibility should probably make these modifiable in the future (as with all hotkeys)
• fix: allow reopening results window if previously closed and needing to be called
• fix: allow reopen sidebar with hotkey after closed
• chore: docs and reordering of refreshSideBar param ordering
