Add routing and add ajax validation

[edsaur]

Hello!

I have started making the project better by applying routing methods and applied AJAX.

ROUTING SYSTEM

This addition fixes the routing in the path from a lengthy one and has the file_name to a short one (example: localhost/customerSide/home/home.php to localhost/home)

• in the .htaccess file I included a configuration where the Apache checks the index.php to what webpage should be opened. In the index.php I've used the switch-case condition to check whether where is the requested page.

THIS IS STILL A WORK IN PROGRESS SINCE the HOME and REGISTER PAGE HAVE BEEN WORKED ON.

AJAX VALIDATION

• To proper have a registration validation without reloading the whole page to process, AJAX has been added.
