Winbar Support + Notes and Discussions; Help Popup + Auto-Open (#133)

- Adds support for toggling between discussions and notes views
- Deprecates the split view shared with both discussions and notes at the same time
- Adds winbar to discussion split, with metadata about resolved and unresolved discussions
- Adds help popups with information about keybindings for all views
- Modifies highlights in discussion tree and default symbol for unresolved discussions

This is a MINOR version bump as the default behavior of the discussion tree is changed slightly. Existing configurations should still function.
