implements an event system for Buffalo

[markbates]

A note about plugin via CLI support:

Because plugins receive their payload via their CLI they get a limited payload of only the items that can be Marshaled.

I wrote a simple “echo” buffalo plugin and here’s one of the payloads it received, it’s the event that is emitted after a RouteInfo#ServeHTTP is run.

Notice, in the below payload, that certiain items from buffalo.App, for example, aren't marshaled. What is left, however, I feel is more than ample to do whatever you want with a plugin.
