Add support for almond.js style AMD loading

[mileskin]

Almond (https://github.com/jrburke/almond) loads only modules with an explicit name. Related: requirejs/almond#49

Dunno if this breaks require.js or something else, haven't tried :-)

From readme:

It usually means that there is a define()'d module, but it is missing a name, something that looks like this:

define(function () {});

when it should look like:

define('someName', function () {});
