Support TypeScript UMD

[xi]

Typescript added support for generating UMD in 1.5. Unfortunately, their style does not yet work with the r.js optimizer.

I added a test case and tried to fix it. It works on my test data, but I feel like the implementation could be a lot more elegant.

I just submittet a CLA.

Do you know if it is possible to just ask them to change their output? I have not tested it to confirm with the r.js optimizer, but I expect this will work and is slightly smaller than their current output:

(function (factory) {
    if (typeof module === 'object' && typeof module.exports === 'object') {
        var v = factory(require, exports); if (v !== undefined) module.exports = v;
    }
    else if (typeof define === 'function' && define.amd) {
        define(['require', 'exports', 'lib'], factory);
    }
})(function (require, exports) {
    var lib = require('lib');
});

Also, some standard umd patterns are here:
https://github.com/umdjs/umd

The reason to create some common patterns is to make it easier for tools to work together, so if one of those could not be used it would be good to know why in case something was missed in their construction. They seem to have worked out well over the years though.

Has been fixed on the Typescript side.
