Overhaul of snakebids create

Use copier instead of cookiecutter
- Better feature set
- Better documentation
- More polished (e.g. typed codebase)

Change starting workflow into a "welcome" workflow
- Pregenerated empty data file based on the tutorial
- workflow reads in the datafiles using generate_inputs and prints a
  welcome message

Allow choice of build systems. App will be immediately installable and
publishable

End-to-end testing of app creation, dependency installation, and initial
run

Validation of email address and app_name. Make app_name and version
mandatory fields
