v0.9.0 (beta) — pairing codes as files, 15 minute codes

What's new

• Pass pairing codes as files. On Add workstation and Join session, Save to file saves the join or reply code as a small text file on a shared network drive or a flash drive. On the other PC, Load code from file (or drag the file onto the code box) reads it. This works alongside copy and paste, the QR code and the printed barcodes. The files are temporary: each works once. Delete it after pairing.
• Codes last 15 minutes instead of 5, so there's time to carry a code file between desks.
• Fixed: a reply code stopped working after about 3.5 minutes in Chrome, whatever the expiry said. It now works for the full 15 minutes.
• Field probe (probe.html): pairs the same way as the app.

Install

Updating a PC that already has the shortcuts: extract the new zip and run the setup script for that system. Sessions, the printer and the workstation name are kept. New desk PC: follow Setting up a desk PC in README.txt (in the zip). offline-checkout.html is also attached on its own for PCs set up by hand: copy it over the old file.

Sessions are kept: there is no IndexedDB schema change. The pairing format is now OC3: 0.9.0 cannot pair with 0.8.x or older. Update every desk PC together, and don't update during an outage. An older desk shows a "different version" message instead of pairing.

Beta

This is a beta. Before rollout, re-run the field probe on the library PCs (the connection handshake changed), and try pairing two PCs through a file on the network share, carrying the reply back after a few minutes. The checks listed for 0.7.0 and 0.8.0 still apply.
