Update dev/prod build process to single command 'gulp'

Utilizing foreman, gulp, and npm scripts, the build process has been
simplified down to just one command, 'gulp'. The one command will start
foreman which will consume the 'Profile.dev' file. Which will call the
npm script, 'dev.' This script will go back and call 'gulp dev' which
completes a series of operations. It will clean out the css folder, copy
over the css files needed from medium, compile the scss files and dump
them into the css folder, kick off a browserify build, then start a
watch on the proper dirs, and finally start nodemon.

All the individual parts of this process has been broken out so that any
dev can call each part on their own. The npm scripts have been bound to
the same gulp commands for a one to one match so that any part in the
process can be skipped by just calling the correct step in the process
and anything beyond that point will be completed as well.

From start to finish:
gulp  ||  npm run gulp  --> From profile to nodemon
gulp build  ||  npm run build  --> clean, copy css, sass, browserify
gulp dev  ||  npm run dev  --> build + watch and nodemon

As for production, 'npm install' and 'gulp build' should be used during
the installation process. Afterward, the 'Procfile' can be used to just
serve the application. This file will start the application with the
.env file in the local dir and calls 'node server.' Also, 'npm run
start' can be used to start the application withtou binding the .env
file. The Profile can be exported to something consumable by systemd or
some other startup system. Or the Procfile itself can be run by using
'foreman start'
