Browserify adapter

Use it as follows:

```javascript
var Opentip = require('path/to/lib/opentip');
var jQuery = require('path/to/jquery/shim');

require('path/to/lib/adapter-browserify')(Opentip, jQuery);
```

```javascript
// jquery shim
require('path/to/jquery');
module.exports = $;
```

Basicly this adapter could also be used for component.js.
But as I don't know how you would
like to have it, I just created this as well.

Tests are not working with it as I didn't figure
out how the test for the component.js adapter works.
Could you please point me into the right direction?
