Actually include HTML head resources. Called through html_post//2 from html_requires//1 after rewrite by html_head_expansion/2. We are guaranteed we will only get one call that is passed a flat list of requested requirements. We have three jobs:

Figure out all indirect requirements
See whether we can use any‘aggregate’resources
Put required resources before their requiree.
