Populate database with dummy data for testing

[Fehings]

We need some dummy data to test the search and browse functionality. Can use generators for this that give us pseudo random data which is formatted to be close to the real thing.

• [x] Generate artificial dummy data (use a generator to make sure the data is similar in form to our real data)
• [ ] Add a couple of data entries with data from the master spreadsheet to ensure we have some real videos in the database that we can use for testing embedding
• [ ] Import the dummy data into the database (either csv import directly or with django handling of imports).
