MultiUpdater support

[PaulSonOfLars]

What

This PR outlines some possible additions to the updater to support running multiple bots at once on the same updater.

This would allow users to easily run multiple bots with the same codebase, as the same program, but with different names.

Impact

• Are your changes backwards compatible? No - many minor method changes.
• Have you included documentation, or updated existing documentation? TODO
• Do errors and log messages provide enough context? TODO
