Laravel 8 + CoreUI 3 update

Changelog is quite big, so it's probably easier to just list the two corresponding (and well documented) pull requests:

Laravel 8 update: #42
CoreUI 3 update: #44

Many thanks to @Daniel-I-Am for making this possible

Changed

• Updated to CoreUI 2.1.16

v3.2.1

Update FontAwesome to 5.11.2

v3.2.0

Removed the necessity for using Yarn while working in this project.

v3.0.0

Update to ensure compatibility with Laravel 6 and higher.

Please note that we've removed compatibility with any version lower than Laravel 6.0.

You can use older, unsupported versions (^2.0.0) of this package to be compatible with Laravel 5.8

We've also tried to adhere to the structuring of the new laravel/ui package to make it as easy as possible to extend this package with the knowledge you already have. The only differences are in the file paths, so please note them.
