feat: Rebase on log buffer (#62)

Now it is possible to rebase interactively from the log buffer with visual feedback. You can rebase one or many visually selected changes.

Supported target modes are: `-o` / `-A` / `-B`.

Limitation:
	- As of now you cannot rebase a whole branch (-b) from the log view.

Bonus from this pr:
	- Now keymaps support different modes
