Add LJ::dhtml to mirror LJ::ehtml (#1811)

* Add LJ::dhtml to mirror LJ::ehtml

Fixes #1737.

Adds LJ::dhtml for symmetry with LJ::ehtml, which applies
HTML::Entities::decode (or equivalently HTML::Entities::decode_entities)
to an input string. Replaces HTML::Entities::decode(_entities) with
LJ::dhtml in the codebase.
