Update example app and demonstrate some other best practices

[rjcorwin]

I was having some issues getting the example todo app running and @vinz243 had a good request in #224 that on application first start it set up some security.

• [x] Add a package.json so modules are available.
• [x] Add a README with todos installation and start
• [x] Disable admin party by creating an admin
• [x] Setup todo database on app start
• [ ] Setup validation
• [ ] Setup users
• [ ] Setup permissions

Getting closer. It now creates an admin and then creates an app database using those admin credentials.

application-server-boilerplate folder is now merged into todos folder

@nolanlawson I may not get to the other items on my checklist so it may be good as is. I could squash the commits in this PR if you like.
