Allows SystemJS users to syncronously import a pre-bundled module. It achieves this by using the synchronous-inspection feature of Bluebird together with a forced synchronous-resolution mechanism that we add ourselves.
The upshot of this is that, whereas you might normally import a module with SystemJS like this:
var System = ; System;
you can instead write synchronous code like this:
var syncImport = ; var m = ;console;
