Fixes #47 - auto generate test events at the CLI

[mhalverson]

Sample usage, from inside the VM:

python3 manage.py generate_and_insert_test_events -n 1000

This implementation is special-cased to just handle Events. If it becomes useful, we can generalize it to other palanaeum.models classes in subsequent commits.

Why don't you simply create new Event objects and call their .save() methods? It'd simply look like this:

for i in range(n):
    event = Event()
    event.date = datetime.date(2017, 1, 1) + datetime.timedelta(days=i)
    event.name = 'auto_generated_event_{}'.format(i + 1)
    event.review_state = random.choice(review_states)
    event.save()

No need to create a temporary file, or call django's loaddata command. It also avoids any primary key conflicts that you currently have.

Sure, will do! There was no reason for choosing loaddata vs event.save(). I am new to django so I just picked the first implementation path that I found in the docs :)

kk, updated the pull request to use the event.save() implementation.
