Refactor for the Future!

This is an epic upgrade for the TECHTONIC Yeoman generator!

🎉 Welcome the new sub generator: techtonic:project!!! 🎉

• The project sub generator will allow one to utilize ESLint and Karma without scaffolding a full-blown web app
• The project sub generator "rolls out the red carpet" for future upgrades such as a "desktop application" sub generator, which will create desktop apps with Electron
• The default behavior of yo techtonic has not changed, now it just runs techtonic:project and techtonic:webapp behind the scenes
• Basically, I separated the stuff that a web app and desktop app share...and named it techtonic:project

Yay, options and stuff!!!

• Refined and reduced prompts. Now there are only 10 questions!
• With all the new options available, it is now possible to completely customize what gets installed and skipped "automatically" (from the command line)
• Each generator now supports command line options! Users and unit tests rejoice!
• Refined details of generated workflows
• Reduced logic and variables inside template files for easier usage outside of generator workflow
• Added JSON utilities to customize files during the scaffold process
• Updated dependencies

Massive "behind the scenes" Refactoring!

• Refactored code for enhanced maintainability
• Cleaned up unit tests for all generators (now with a lot more promises)
• Created robust visual regression test suite with Nightmare.js and node-resemble that tests the quality of all the generated application permutations!!! (I am kind of excited about this one)

...probably a ton more stuff...it has been quite a journey getting to v4.0.0 😁
