Git-aware notification does not work if branch not defined

[ilkka]

I've purposefully not set :branch in my Capfile, to be able to deploy the currently checked out branch. This causes notifications to fail, however, wth

    triggering after callbacks for `deploy'
  * 2013-10-15 10:47:00 executing `flowdock:notify_deploy_finished'
    triggering before callbacks for `flowdock:notify_deploy_finished'
  * 2013-10-15 10:47:00 executing `flowdock:set_flowdock_api'
Flowdock: error in sending notification to your flow: undefined local variable or method `branch' for #<Capistrano::Configuration::Namespaces::Namespace:0x007fcff24d2168>
  * 2013-10-15 10:47:00 executing `flowdock:save_deployed_branch'
  * executing "echo 'HEAD' > /path/to/myapp/current/BRANCH"

I think the process should be smart enough to git rev-parse --abbrev-ref HEAD if the branch has not been given.

@ilkka I've since moved on to capistrano 3, but can you check if the problem persists in this branch?
