- Patch 8756 by Morbus:

* improves the doxygentation and help text.
* deletes comment_admin and comment_page; using proper callbacks instead.
* related/modified callbacks/menus/functions were tweaked to not use arg() at all.
* the "settings" subtab was weighted to -10 so it'd appear first (in prep of JonBob's local default).
* moderation pages weren't properly showing defined votes or thresholds; fixed.
* when moderation votes or thresholds didn't exist, no error stating as such was shown; fixed.
* we show "submit votes" on the moderation votes page only when votes actually exist.
* fixes the (broken in CVS) comment/reply and comment/edit features.
* fixes the (broken in CVS) "save settings" for comment view options and comment moderation.

In addition I:

* fixed a couple warnings introduced by Morbus' patch.
* fixed a couple translation bugs.
* fixed comment_node_url().

I also found that:

* the collapsed comment views (i.e. 'threaded list - collapsed) are broken.
