Messages and Prefs update

Messages updated to give new full reverse chronological order.

When working on this noticed that prefs and users menus really needed an overhaul to fix inconstant tiles.  This meant changing the wording to match other sections and adding the user nickname and hid where needed.

This also made me notice that the Messages and Submissions prefs did not use the admin_block like the users.pl prefs.  Needed to fix the template related to this as well as the users.pl file to allow the admin_block to pass the form vars to the two added prefs pages proper pl files.  This was done using the slash redirect command, but this had to happen before any other slash calls in user.pl because if page rendering started, the redirect does not work.

All of this work required some minor changes in the css and related templates.  Did some other while I am here work as well that was really not on the issues list.  

But the work here fixes some more issues from #19.  Still need to go through all of the prefs pages and make them look pretty and to remove dead wood.
