Upgrade notes for Bweb

Update from 3.0 to 4.0/5.0
---------------------------

Nothing to do

Upgrade from 2.2.Y to 3.0
-------------------------

 - Template location is a bit different :
   2.2.Y)
      /../share/bweb/tpl          # english
                     fr/tpl       # french
                     es/tpl       # spanish

      template_dir points to one of them

   3.0)
      /../share/bweb/tpl/en       # english
                         fr       # french
                         es       # spanish

      Now, template_dir points to the template root, and
      we use a new option "lang" to use the right location

      template_dir=/../share/bweb/tpl
      lang=fr
           es
           en

 - If you are using english template, you have to use
   bweb/lang/en/tpl/*.tpl instead of bweb/tpl (see INSTALL)
 - Add the Date::Calc package to your perl library
 - Add user, new job overview and bresto tables to your catalog
