Git Branch merge!

[Xasin]

Let's see how this works out, eh?

Git-Restart is finally looking like it won't blow up right in my face, and I think that's just wonderful!
So far, it manages to automatically detect git updates, fetch the new data, update the repository, re-start tasks that are affected by this update, and it also reports failures and the likes~!

• Error message reporting still needs to be handled, possibly by using gists or by sending an MQTT message
• Maybe a "return to"behaviour should be added
• code documentation - please.
