Hey,

I've tried the example from the `README.md` and installed the app as described.
Unfortunatley it fails because the HTML docs has no HTML-Form named `form`.

```

raise FormNotFoundError("no form matching " + description)
mechanize._mechanize.FormNotFoundError: no form matching name 'form'
```

What I discovered so far is that `follow_link` (on line 72) with "Advanced search" is responding with the main page and not with the "rendered" response of "Erweiterte Suche".

```python
response_search = self.browser.follow_link(text="Advanced search")
```

Link-element with title "Advanced search" on main page, that is included in the response:
```html


Advanced search

```
Could someone with more knowleadge of this lib check if this was working with the current website of Handelsregister or is there a major change that breaks the lib?
I'm glad to help solve this issue, but before I try to overcome the JQuery rendering with Selenium I'd like to know if mechanize was before able to handle this behaviour?

Greetings David
