Install Rails w/PostgreSQL

This is the state of rails after the initial installation, and nothing
more. Database was set to use postgresql:

    rails new depot -d postgresql
Configure database.yml

  - DRY the file.

  - Set username to computer login.

  - Add localhost to development.
Ignore Heroku environment(.env)
Create Heroku/Foreman Procfile

Start with the basic web process.
Add 'thin' and 'foreman' to Gemfile

Thin should now be the default rails server. We'll see.

I could simply gem install foreman, but I like requiring it better.
We'll see how this works out in the long run.

Also moved the jquery gem higher, so that all general gems are above any
group-specific gems.
Reconfigure Procfile & Environment for Thin.

Added a more robust command to launch thin from the Procfile. I'd like
to learn sometime what the difference is and why this helps. But for
now, it works.

Added a stdout change to the development environment. Again, it'd be
nice to research this further, but for now, I'm moving on.
Merge branch 'setup_rails' into develop
