Title: Simplify TFClient and allow unsubscribe by key

Several simplifications + one features

You can now do

```js
var tfClient = new ROSLIB.TFClient({
ros : ros,
//fixedFrame : 'world',
angularThres : 0.01,
transThres : 0.01
});

tfClient.subscribe('odom', function(tf) {
...
});

tfClient.unsubscribe('odom');
```

TODO implementing via event emitter?
