v0.5.6-beta.2

Desktop

• Multiple windows. Launching Klarinotte while it's already running now
  opens a second window instead of failing to start. File → New Window
  (Cmd/Ctrl+Shift+N) does the same, and each window remembers its own notebook.
• Application menus work properly and no longer intercept keys meant for the editor.

Shared notebooks

• Removing someone from a shared notebook now more robustly revokes their access.
  Rotation also completes if it's interrupted, and leaving a notebook yourself
  triggers it too.
• People invited before a key rotation can still open the notebook afterwards.

Search

• Indexing for semantic search no longer stops at the first note it can't process.
• Large notes can now be indexed at all — previously they'd run for minutes
  and time out.
