Ability to see code history and changes

[michaelzolo]

Would be saving tons of time if I could say something like "write unit tests for the code changes that I've done in the past hour". Or even some simplified or manual ability to track code changes and to act upon those. Or instead - making Bito see the difference between the current code before the uncommitted git changes (currently it's only able to see that), and comparing this to the current uncommitted changes waiting.
