[Epic] Polish Core Datasets

[zelima]

As a PM, I want to review core datasets and make sure all of them are up to date so that I'm sure in their quality

As a PM, I want to re-run and make sure scrapers/scripts are working fine so that I can update data anytime

As a PM, I want to translate scrapers/scripts into dataflows, where possible, so that we use our tools to get the data, plus we can easily update them

As a PM, I want to review READMEs of the core dataset and update where necessary, so that I (and users) are sure that dataset descriptions are accurate enough

Acceptance Criteria

• We have the latest data for all core datasets
• We have all of the non-complex scripts working OK (unless the source is broken)
• We have the missing sources and complex scripts fixed up
• READMEs are up to date
• We use dataflows to get the data
  • Automated by Travis
