Real hook system

[jsilvestre]

Currently we have two hooks: beforeStart and afterStart. In my experience, it's not enough. I mean I never get what the hook I want where I want. Sometimes I need it before plugins are loaded, sometimes right after, .... so I end up not using beforeStart and afterStart (or rarely).

I suggest we turn americano (the object) into an event emitter that triggers events at each step of initialization:

• before anything happens
• before configuration loads
• after configuration loads
• before plugins are loaded
• after each plugins has been loaded (with the plugin name)
• after plugins are loaded
• before routes are loaded
• after routes are loaded
• before http server actually starts
• after http server actually starts
• after everything happens

Many events are redundant here but this adds semantic. The callback for these events could be declared in an ./server/init.coffee file or in the configuration (if we feel the configuration events are not relevant).

Good idea :+1: !
