Implement back and forward functionality

[SebastianZaha]

Look into vscode back / forward navigation commands, and bind them to something emacs-like.

It seems emacs did not have something "standard" for it, and has a local-ring and a global-ring, we could choose to only bind the global one, as it seems to make more sense.
