Support `catch` in `Promise` shim about libjass HOT 2 CLOSED

I understand that SimplePromise is a little different from SimpleSet and SimpleMap in that it's exposed more openly from the libjass API, whereas the other two are used completely internally. However I don't want to make the shim more complex than libjass itself needs it to be internally.

libjass only uses SimplePromise if global.Promise is not defined. If you want the promises that libjass's API returns to have more features, then you should give it such an implementation yourself, say, by including bluebird. For the same reason, if the browser / runtime has a native promise implementation, libjass will automatically use that.

If for whatever reason you're unable to have global.Promise be available for libjass to use at the time you load it (say your implementation is loaded after libjass is, or say it doesn't assign itself to global.Promise), you can still override the promise implementation used by libjass by setting libjass.Promise, eg: libjass.Promise = require("bluebird"); Make sure you do this before using any libjass API that returns you a promise, since I do not guarantee that an instance of SimplePromise works with instances of any other type of Promise.

Regarding:

Make sure you do this before using any libjass API that returns you a promise, since I do not guarantee that an instance of SimplePromise works with instances of any other type of Promise.

Since SimplePromise follows the Promises/A+ spec correctly, it should in fact work with instances of other types of Promise.

The recommendation to use a more featured and performant library still stands.
