Update the emoji image packages to v16/v17 (unicode) they were at v14 ... so that added a few new ones. Also chose to use GitHub naming for the :name: can't remember what was used the first time, but there are really no defacto standards ...
Fixed a strange dispatch path that allowed the dispatcher to maybe bypass the action controller which was not noticeable but could have some less than ideal side effects.
Fixed a couple of minor issues from the previous PM refactor (actually one issue was pre ElkArte) due to some wrong boolean math. Ah well ... generally harmless.
