Refactor: Separate user facing tasks from server side deployment logic

[chrisjsimpson]

Separate __init__.py from main.py

• __init__.py exposes front end forms to the user creating their site
• main.py actually builds the new site

They should be separate entirely because they have to be deployed independently anyway.

[ ] - remove deployment logic from module_builder
