release 3.4

Major updates, including:

• new license: LGPL (allows for easier use of Tale as a library)
• changes in ParseResult to avoid creating multiple lists of parsed arguments (who_order is gone), and to access the most often used parsed entities
• shop fixes
• added simple ssl support to wsgi webserver
• mudobject.story_state added
• games now saved via serpent instead of pickle, loading no longer generates a lot of duplicate detached objects
• improved the login and character creaton procedures
• optionally uses prompt_toolkit for a nicer command line experience
• added some more behaviors to the circle story's inhabitants
• money can now be dropped on the floor (as an item) and picked up
• items now have a 'takeable' property so you don't have to override allow_take_item everywhere.
