Add DataFaker support

[Fishbowler]

Proposed changes

• Replaces the backing of existing random commands with DataFaker
• Adds some new random data commands InputRandomCityName, InputRandomCountryName, InputRandomColorName
• Add support for freetext evaluation via DataFaker with a new InputRandom command, e.g.

- inputRandom:
    type: "animal.genus"

This is using DataFaker's evaluation, which gives an added benefit of access to methods that take parameters. Nice for advanced usage, but a little ugly. e.g.

- inputRandom:
    type: "number.randomDouble '2','10','99'"

Testing

With a text box selected, run:

appId: com.example.notused
---
- inputRandom:
    type: "animal.genus"

- inputRandom:
    type: "number.randomDouble '2','10','99'"

Have also tested that error handling works when the type isn't a supported DataFaker provider method.

Issues fixed
