Auto Updating

[unsecretised]

Since RustCast has been growing quite quickly recently, a good idea would be to implement an auto update system

Hey I would like to work on this issue, can you give me a brief description of the problem?

Using something like the self update crate, it would be nice if rustcast would be able to let the user choose to update or not and add the update item to the tray icon
