Create app with a model to store latest event data

[estebistec]

Action items:

• Create model to keep latest meetup data, in case meetup is ever down or we exceed rate limit (seems unlikely, but I somehow just did it)
• Model could mean Django ORM (SQL) or persistent redis data. TBD
• Create model to override event photo with custom photo URL
• Setup admin interface behind login so that data can be manually updated if need be, and the event photo overrides can be managed.
• Add Django-style backend interface [1] that abstracts away the usage of the meetup API vs. model fallback. This should make our views resilient to any issues with meetup.com's availability or our rate limit.

Also, from the design [1], need to show a logo for the source of the photo below it.
