Post a new review if there are no candidates to update.

This can happen e.g. if you forget to publish your review. Or if you haven't
posted any.

I also improved review request description formatting a bit.
Initial init command implementation.
Added `init` command to git flow2 and installer.

Plus fixed referring to `gitflow2.yml` instead of `gitflow.yml`.
Various `git flow2 init` fixes.
Various improvements.

 * Make sure repo is initialized before running commands.
 * Handle empty Pivotal Tracker.
Make sure feature is estimated before we try to start it.

Also fixed the "allowed stories" regexp.
Removed git hook code setup code from `feature start`.

It's dealt with in `init`.
Start story in PT and set owner even if story branch exists.
Added info echo that RB is slow...
BASH commit hook that deals with `git commit --verbose`.
Don't fail if user accepts to install hook.
Don't let hook output anything unless necessary.
Moved echo to its proper place.
Add a new line before injected lines.
Change-id might contain letter too, duh.
