Containerized the application

Containerization, and a slew of changes to support using docker for a development environment, and to deploy via CI/CD tools. This is a breaking change, since the file structure is now substantially different.

2.2.1

• Breaking changes since 2.1.1. Method signatures have changed for the Aspect type in the CRPS package, and I updated the basic aspect types to reflect it.
• Artisan command for generating boilerplate for Aspect Types. (php artisan coldreader:new aspect_type)
• UsersAspectsJobs for queueing
• firstrun.php file to make installation easier
• Added some basic tests to phpunit.xml
• Moved most of the installation process to an artisan command. (php artisan coldreader:install)
• Added a quicky artisan command for running migrations on the system within a Docker container, to facilitate testing with Docker.
• Corrected method signatures for Aspects edit_form method
• Lots of style fixes
• New versions of php libraries in the composer.lock

First stable release

This is the first stable version that is ready for public consumption. There are certainly still tons of bugs, so if you find one, please report it as an issue on this repo. Thanks for trying it!
