Fix qalculate backend with recent versions of libqalculate The latest qalculate version prompts about enabling the "autocalc" feature at startup and expects user input, which makes the cantor interface hang.

Very good! I'm returning to reinforce the confirmation that one of the Cantor updates resolved the issue of integration with Qalculate; for now, problem solved - my thanks to everyone involved.
