----------------

  [thet]

- Remove ability to add property parameters via a value's params attribute when
  adding via cal.add (that was only possible for custom value objects and makes
  up a strange API), but support a parameter attribute on cal.add's method
  signature to pass a dictionary with property parameter key/value pairs.
  Fixes #116.
  [thet]

- Backport some of Regebro's changes from his regebro-refactor branch.
  [thet]

- Raise explicit error on another malformed content line case.
  [hajdbo]
