Add presence heartbeat to keep bot shown as online

Adds a background asyncio.Task that calls set_presence("online") every
60 seconds to keep the homeserver presence status fresh. On startup the
bot sets itself online and spawns the heartbeat; on shutdown the task is
cancelled and presence is set to offline before closing the client.
