added mailer, figaro and devise to basic-template.rb

I added a template that can used when creating a new rails app that installs and configures all the basic gem.

Simply run 'rails new FOO_APP -m https://raw.githubusercontent.com/LaunchPadLab/process/master/DevNotes/Rails/Templates/basic-template.rb' and voila!
 
This is following DevNotes/Rails/new_app.md and DevNotes/Testing/setup_rspec.md.  Please take a look and let me know if there are additional items I should include in a basic template, optionally or required OR if there are specific templates I should create.  In addition, I am not sure if the mailer is completely configured.

It also not the most efficient implementation at the moment, but I can fix that going forward.
