Simple Alert Dialog

[Williamrai]

What does this do?

This adds a class called SimpleAlertDialog. The purpose of this class is to simplify the creation and display of alert dialog and to centralize the creation of AlertDialogs into a single reusable class.

Why is this needed?

It helps to avoid doing the repetitive code often needed with setting up alert dialog and reduce boilerplate code. It provides customizable Dialog elements like title, message, icon, buttons and theme. Also adds a delay feature.
