Add a {% render_like %} template tag

{% render_like like %} renders the given like and prints it in the
template. The template that it uses depends upon the liked instance, and
is either:

* phileo/<app>/<model>.html
* phileo/<app>/like.html
* phileo/like.html

This allows for custom like templates on a per model and per application
basis.
