Implement public file sharing

An HTML form is now added next to each regular file, that generates a
POST request. Then, slcl replies with a HTML document with a link to the
public resource (which are implemented as symlinks).

Limitations:

- For now, only regular files can be shared i.e., sharing directories is
not possible. While feasible, it still requires a larger refactor to
list_dir and resource_layout, so that read-only access to the directory
is provided to anonymous users.
