gateway: Refactor for a better concurrent API
This commit refactors the whole package gateway as well as utils/ws
(formerly utils/wsutil) and voice/voicegateway. The new refactor
utilizes a design pattern involving a concurrent loop and an arriving
event channel.

An additional change was made to the way gateway events are typed.
Before, pretty much any type will satisfy a gateway event type, since
the actual type was just interface{}. The new refactor defines a
concrete interface that events can implement:

    type Event interface {
        Op() OpCode
        EventType() EventType
    }

Using this interface, the user can easily add custom gateway events
independently of the library without relying on string maps. This adds a
lot of type safety into the library and makes type-switching on Event
types much more reasonable.

Gateway error callbacks are also almost entirely removed in favor of
custom gateway events. A catch-all can easily be added like this:

    s.AddHandler(func(err error) {
        log.Println("gateway error:, err")
    })
