Tag to list animals

[StefanOfDenmark]

This is a great plugin that has already made my life easier :-)

I have a request though: I would like the sidebar in the farmer wiki to show a list of animals.
How about a tag to list the animals in the farm? Just like on the Info tab, but as a tag that can be used where needed. Or is this possible with a simple hack?

I tried

<php>
  $farmer = new admin_plugin_farmer_info();
  $farmer->animals(1);
</php>

But then I only see the page header and a blank page.

Best regards
Stefan
