Add Recover

#126

//
// Recover ( disabled by default, unless a custom Recover handler is set )
// We might enable Recover by default with "500 Internal Server Error" in the future
//
func main() {
  app := fiber.New()
  app.Get("/", func(c *fiber.Ctx) {
    panic("I panic")
  })

    c.Status(500).Send(c.Error()) // => 500 "I panic"
  })
  app.Listen(3000)
}

//
// Context error
