v1.0.0

Yay! We've gone version 1.0 now! Development is probably going to stabilize
around where we are now. I don't think there's much more to be added, but
feel free to prove me wrong :)

Now all we have to do is make minor code changes to keep it stable. (and add some
support for different formats)

• Simplify option descriptions.
• Catch connection failed error.
• Remove --all-branches option, now it is the default.
