The Bookmarklet Maker should strip JavaScript code comments first

For the following code:

```js
// Show an alert window
alert('hello world');
```

I get a the following bookmarklet output:

```js
javascript:(function()%7B%2F%2F%20Show%20an%20alert%20window%0Aalert('hello%20world')%3B%7D)()%3B
```

but I think the JavaScript comments should be removed, and get

```js
javascript:(function()%7Balert('hello%20world')%3B%7D)()%3B
```
