POD: Create anchor for every =item directive
POD: Create anchor for every =item directive

Setting anchor_items to true is needed for creating link to specific =item
directive. By default Pod::Simple::XHTML module does not enable it.

Webpage https://metacpan.org/ for POD documentation has it already enabled
and linking to =item directive is working fine.

Lot of POD documents already link to =item directives and without setting
anchor_items to true documents are semi-broken on GitHub.
