provide a way to override dependencies of module when doing require

[snimavat]

Currently there's no way to override dependency of a module when doing require.
It would be great if there was way to do some thing like

    p.define("someCtrl", ["$elem" ,"module1", "module2"], function( $elem, mod1, mod2 ) {
        // Launch application!
    });

$elem = $("#div");
pod.require("someCtrl", {$el, function() { return $elem}}) //override $elem
