[PATCH 5/9] docs: newapi: Don't generate empty <div> in template for ACL permissions

[Peter Krempa <pkrempa@xxxxxxxxxx>]

If an API has no ACLs an empty <div class='acl'/> would be generated
which is mis-interpreted by browsers when creating DOM to nest any
subsequent elements under it.

Don't generate the ACL section div unless it will be filled.

Best viewed with 'git show -w'
