/**
* Favorites widget, designed for use with a nextmatch widget
*
* The primary control is a split/dropdown button. Clicking on the left side of the button filters the
* nextmatch list by the user's default filter. The right side of the button gives a list of
* saved filters, pulled from preferences. Clicking a filter from the dropdown list sets the
* filters as saved.
*
* Favorites can also automatically be shown in the sidebox, using the special ID favorite_sidebox.
* Use the following code to generate the sidebox section:
* display_sidebox($appname,lang('Favorites'),array(
* array(
* 'no_lang' => true,
* 'text'=>'<span id="favorite_sidebox"/>',
* 'link'=>false,
* 'icon' => false
* )
* ));
* This sidebox list will be automatically generated and kept up to date.
*
*
* Favorites are implemented by saving the values for [column] filters. Filters are stored
* in preferences, with the name favorite_<name>. The favorite favorite used for clicking on
* the filter button is stored in nextmatch-<columnselection_pref>-favorite.
*
* @augments et2_dropdown_button
