Don't export namespace Dexie. It's idea was to help typings for those using Dexie as an iife. But 2 problems: 1. It prohibits auto-importing Dexie from "dexie". 2. It doesn't export Dexie for iife correctly:   * Doesn't support new Dexie("dbname")      - must be new Dexie.Dexie("dbname").

This change may be breaking for those that have relied on it. But they must be very few because we've never documented to create a Dexie instance like that anyway.
