Inject configured dependencies into legacy factory function

[unscriptable]

At the moment, the factory function only receives the module/script name. If we inject the dependencies, as well, devs can solve more compatibility problems. For instance, some libraries don't export a global var when they detect and AMD define(). This prevents a legacy script from importing the library. Case in point: jquery.flot.time.js uses timezoneJS.

If flot.js's legacy config looked like the following, we could make this work:

"flot": {
    "requires": [ "timezoneJS" ],
    "factory": function factory (id, deps) {
        window.timezoneJS = deps[0];
        return window.$.plot;
    } 
}

Feels kinda hackish. :(

As a complement, this it the declaration of the corresponding lib (and its definition as AMD module), timezoneJS, where we can see timezoneJS not being attached to root when AMD is detected. (Much kudos to @unscriptable for helping me figuring out what happened)

I added a fix and some tests. I'm seeing intermittent failures on some unrelated tests in that test harness. Strange.
