Version 1.1.0

Added

• Requests timing out in 2 minutes (can be overridden by subclassing the ElvisClient),
  previously, there was no timeout and requests could hang for long time causing resource
  leaks
• Add helper to provide choices tuples from Enums (can be used with Django)
• This changelog

Changed

• Date fields are now properly parsed to datetime
• Elvis proxy exception formatting is improved so that exceptions can actually
  be read

Fixed

• ElvisModel was mutating its constructor argument, sometimes causing undesired data changes
• Getting transport orders now works in python 3
