1.4.1

The v1.4.0 zip that is already published contains the updater that trusts the
repository's own browser_download_url — the one that reports a plain-HTTP raw
IP. Anyone who installs 1.4.0 keeps that until an update arrives over exactly
the address it gets wrong. It works today, because that address happens to be
reachable, which is the reason to close it now rather than leave it working by
luck.

+* The update check now builds the download address itself instead of using the one the repository reports. The repository was reporting a plain-HTTP address on a raw IP, which would have meant downloading plugin code over an unencrypted connection to an address that is free to change. Anyone on 1.4.0 gets this automatically with the next update.

 = 1.4.0 =
 * The plugin now updates itself. WordPress checks the plugin's own release feed and offers new versions in Plugins and Dashboard → Updates, so an update no longer means uploading a zip by hand. The per-plugin "Enable auto-updates" link works too.
 * Tested against WordPress 7.1 and WooCommerce 11.1, and against the next release of each, so an update to either is checked before it reaches a shop rather than after.
