Subject: [PATCH] Add Event class.

Event class is based on EventSystem's Event class. You can see
its implementation on https://github.com/AnidemDex/Godot-EventSystem

Using 1.4.3 version.

Some deprecated members were removed directly, but those that will not be used
by the plugin remains untouched.
