- removed previous 'typification' of input as it needs it is typed by
  module as strings and needs to be output as strings, making it
  useless.
- now checks for vtype and value against None when question is specified
- simplified set_selections as vtype and value should have a string
  value going in.
- added example of querying questions for a package
- added module requirement of question,vtype and value being required
  together.

- field names are more consistent with debconf
- values are now 'booleanized' or accepted as list/set objects when
  pertinent
- updated docs to reflect all of the above and debconf cli tools
  required
