QuestionPattern draft implementation

unnecessary import
script to pull in patterns

run "python manage.py update_patterns" to make the magic happen. example
output:

    $ python manage.py update_patterns
    Created Module(id=1, pymodule=comod_example)
    Created QuestionPattern(id=1, module=1, pattern_str=is {person} a werewolf?)
    $ python manage.py update_patterns
    Loaded Module(id=1, pymodule=comod_example)
    Loaded QuestionPattern(id=1, module=1, pattern_str=is {person} a werewolf?)
dummy module mockup now works.

properly uses external civomega-mod-example repo and python library and
does all the python magic to execute that code! AMAZE.
