Changed all status to start with Uppercase letters, made 3 properties required.
Changed all the status to start with Uppercase letters because they are
publicly visible. Also changed required=True to False for created_by,
modified_by property to allow site admin to create and modify tasks. Also
changed required=True to False for history to allow history not to be written
until the task is published.
# Performance note: I benchmarked this code using a set instead of
# a list for the stopwords and was surprised to find that the list
# performed /better/ than the set - maybe because it's only a small
# list.
