Completing adding all doc for HTML PIs. Added "see also" sections

with links to related global params, plus links to DocBook XSL: TCG
Also tried out adding some additional doc to param doc for the
textinsert.extension param that back-references the PI
documentation, plus added some TCG links there too.
