Release 1.6.0

• merge pull request #13 which fixes a problem with dates
  Staging tags were previously created with Date.today, which is the computer's date, which was causing issues with people from different timezones deploying a application.
  This fixes this issue by using instead Time.now.utc.to_date

• added the Gemfile to the project also . Seems was missing , usually the Gemfile is part of source code , only the Gemfile.lock for gems should not be committed.

Release 1.5.7

• fixed a error with "NoMethodError: undefined method blank?' for staging-:String" when executing

  cap staging gitflow:cleanup_tags

without having ActiveSupport required in Capfile

Release 1.5.6

• added task for cleaning up old tags that can be used to clean the tags , the task has to be manually invoked from command line if is needed.
