Fix missing parenthesis in Edit Bio and Wiki empty page
Fix multiple pages and code to start/end <div> sections properly.
In the Summary page, add line breaks to the “About this server” widget to make it more readable.
In contact view (msg_display) fix missing address label title (invalid variable used) and use variables for other labels instead of hard coding.
When displaying Contact address, remove blank lines if P.O. Box or street fields are blank.
subst.c: Expand ITEM format X to allow appending text after a non-blank ITEM value.  Used to add line breaks only on non-blank lines, etc.
download.c and static.c: Fix invalid reference to blank gif because the output function added the request line from original image to the link which is invalid.
