Improve code organization

[rotexdegba]

• Eliminate redundant code and make use of new php 7.2 and 7.3 features wherever possible.
• Look at using a package like climate for cli operations.
• Use Rector and Psalm for code enhancement
• Look at vanilla laravel projects to get ideas of best practices to incorporate

Made some progress here. Removed things like zurb foundation and some other stuff like jquery that used to ship with this framework. Things are more bare-bones now. Also removed unnecessary methods & helper functions. This will continue to be an ongoing exercise.
