removed search row code

Extracted div row containing the search code; saved it in a TXT file in
the root folder.
Removed top div row for Members

Removed the div for Members as that will be handled by the menu items.
Decided to leave the Background content there to "fill" the home page,
and thus allow removal of that item from the menu (see next change).
Removed Background menu item

As the content for this is remaining on the home page, no need to have a
menu item for it!  Also, this makes the menu a 4-item affair which looks
better in all views.
Background Image and Jumbotron adjustment

So I got the background image added.  Fifty percent transparent seems to
be nice for reading text while still conveying mood.  I also removed the
jumbotron div and replaced it with a regular row since it was hidden
after adding the image background code.  I tried different placements of
the code to fix, to no avail.  It's probably a CSS conflict.  Just
adding a fresh DIV at the top recovered the text and image without all
the hassle.
