Initial code to handle lifecycles and events in addons

This provides the invocation of predefined methods for lifecycles and events
 - prelanuch : invoking prelaunch() in an addon when app-control is emitted
 - suspend : invoking suspend() in an addon when suspend is emitted
 - resume : invoking resume() in an addon when resume is emitted
 - quit : invoking quit() in an addon when before-quit is emitted
 - arrowup : invoking arrowup() in an addon when arrowup is pressed
 - arrowdown : invoking arrowdown() in an addon when arrowdown is pressed

It's only an initial code and focused on the logic to call each method.
