(issue-7) events models database

[ultra-passion-fruit]

Resolves #6 #7 #13 #19

TLDR: Deleted separate app structure (may regret later) and put all into one main app (hence why so many deleted files). Main benefit is one single urls.py where you see all routes on website (nothing hidden anywhere). Drawback is single models.py is getting rather enormous.

Summary of Changes

• Added Event model
• Added EventSession model
• Added UserProfile model
• Added ExecRole model
• Added Card model
• Added Container model
• Added Sponsor model
• Added admin.py forms to edit all models + hooked up to website interface.

Running Instructions

1. From the /jsa dir, create the superuser by running seed script
   python manage.py seed

2. Start development server for local viewing
   python manage.py runserver

3. Navigate to http://127.0.0.1:8000/app/ and login with newly created user

• username "admin"
• password "admin"

4. Then, build Events and Sessions as follows from screenshots, because I did not have time to make a script to do it. But also, you get to learn how to use the application as you do!

Then hit SAVE. This will create the "Japanese Conversation Group" event. ABSOLUTELY NECESSARY since there is a link in the nav that points to the /japanese-conversation-group. This will generate the completely editable page that looks like:

5. Then, create the session for the JCG event:

This will generate the page that looks like:

Note how this session is associated with the JCG event.
