Alpha stack

[bradgessler]

When the server boots after the Alpha stack is executed via monolith new, I should see the page from app/content/pages/index and have a way to share my email address so I can get updates from the service when it becomes available. Here's what needs to be done.

1. Complete the issue at Create rails g sitepress:install task sitepress/sitepress#12 and add a Thor task to run rails_command "generate sitepress:install" for the alpha template
2. Initial Pundit policy and wire into controllers for everything to be secured, by default
3. ApplicationModel should be created in the app/model directory that makes it easy to create non-AR backed models.

Notes for future gems

This won't make it into the initial release. Currently the Alpha stack is missing a lot of things. In the future by default Alpha should:

1. Have a sane default for open graph images so sharing is great. Relevant too is a sane way to deal with page titles, etc. for layouts.
2. Open source the ViewComponent form library I started working in and include that
3. Open source the Resource libraries I started on ThingyBase and include that
