Adds File menu actions to save the running Sud's schedule to a local sud.json and to replace it from one, via the Sud websocket channel's new Download/Upload messages. File dialogs are opened up front on the GUI thread; the actual read/write happens off the websocket recv callback, which runs on a worker thread and must not touch Qt itself. main_window.py is regenerated from brewpi.ui via pyuic5 5.15.11, which also picks up an unrelated pre-existing drift (the default URI had fallen out of sync with the .ui source).
