Plugin basefile that includes `./inc/load.php`
Here I just load the text domain in a old fashion so it working to
internationalize the error message, and throwing a very clean message
using the WordPress iFrame to it's maximum.

Then just load the `./inc/load.php` that loads all the Namespace files
after we already check the 5.3 comparison.
Loads and Autoload required files
Better organize the base file, and add some comments
Auto require all the files that comes from the  folder
Start to define the Plugin class; Namespace
Instead of auto loading, I will do the require myself, better control.
