mjollnir_ 0d06b6fda7 MDL-16423 - big refactor of the way callers interact with the portfolio code
added two new contract methods to the caller class, load_data and expected_callbackargs (static)
this means that the base class is the only place that needs a constructor
and that no data loading happens in the constructor
this in turn means we can check callback argument validity much more lightly

also completely remoted portfolio_add_button function and replaced with a class
as the argument list was getting out of control.  it's now much more readable.

ACTIVITY MODULES
----------------

These are main modules in Moodle, allowing various activities.


Each of these modules contains a number of expected components:

  mod_form.php: a form to setup/update a module instance

  version.php: defines some meta-info and provides upgrading code

  icon.gif: a 16x16 icon for the module

  db/mysql.sql: an SQL dump of all the required db tables and data
 
  index.php: a page to list all instances in a course

  view.php: a page to view a particular instance

  lib.php: any/all functions defined by the module should be in here.
         constants should be defined using MODULENAME_xxxxxx
         functions should be defined using modulename_xxxxxx

         There are a number of standard functions:

         modulename_add_instance()
         modulename_update_instance()
         modulename_delete_instance()

         modulename_user_complete()
         modulename_user_outline()

         modulename_cron()

         modulename_print_recent_activity()
