Support multiple named automations

[TwitchBronBron]

#499 introduced the automation panel. However, it only includes a single saved automation flow. It would be nice to have the ability to save/load/delete multiple automations by name. I'd envision this being some type of dropdown where you can pick from a list, or click "save" to save the current one or replace an existing one.
