Started writing a little test suite.

There where a few changes to existing code:
- container.Data.__[set,del,get]item__ methods now raises
  exceptions. They have to be caught in pynote.command. [TODO]
- container.Data.__init__ now gets a data_file argument. This
  can be used to test the class in action without destroying any
  production data.
