html content DOM action callback function selector

selects a callback function for libdom to call based on the type and phase. dom_default_action_phase from events/document_event.h

The principle events are: DOMSubtreeModified DOMAttrModified DOMNodeInserted DOMNodeInsertedIntoDocument

Returns: callback function pointer or NULL for none
