Change prefs_titlebar to add proper tab menu for SN prefs

Removed unneeded help page and instead setup prefes based on what is
currently usable on SN.
Reorganize main menu to reflect preference changes

Simplified menu to have single link to Prefs.
Reorganized menu order.
Simplified names of different options to reflect the pages they go to.
Made capitalization consistent.
Changed footer links to mirror main menu.

This is a fix to allow users of low bandwidth option to be able to
still see all of the main menu options.  Although this is not optimal,
it is a quick fix or these users.
Style tabbed menus.

Fixed an issue with base.css where tabbed menus were too small due to
changing the size surrounding divs text to a smaller size previously.

Style the tabbed menu (#usermenu) in slashcode.css to show a tabbed
interface.

Overrides on slashcode_lite.css to make the tabbed interface less
intrusive.
Fix display_prefs template for messages

dsiplay_prefs was missing the titlebar and generalbody div.  Looks like
it was set up for a modal dialog box. Since we are not using these,
needed the other above fixes.

Also reworded the text to eliminate  the text about options that are
not in use.

Also deleted a large section that was already commented out.
Add p tags to text on changePassword template

Added p tags around the text on the changePassword template so that
error text will be displayed better.
Add H3 tags around error codes for changing password on data template for logins

To make the error/success text more visible, added h3 tags around the
data that is inserted into the form when processed by the login.pl.

There may need to be others that need the same treatment. saving this
for another time.
