/*
 * smarty_function_button: Display a Tiki button
 *
 * params will be used as params for as smarty self_link params, except those special params specific to smarty button :
 *  - _icon: DEPRECATED previously used for file path for legacy icons
 *  - _icon_name: use icon name to show appropriate icon regardless of iconset chosen
 *	- _text: Text that will be shown in the button
 *	- _auto_args: comma separated list of URL arguments that will be kept from _REQUEST (like $auto_query_args) (in addition of course of those you can specify in the href param)
 *                    You can also use _auto_args='*' to specify that every arguments listed in the global var $auto_query_args has to be kept from URL
 *	- _flip_id: id HTML atribute of the element to show/hide (for type 'flip'). This will automatically generate an 'onclick' attribute that will use tiki javascript function flip() to show/hide some content.
 *	- _flip_hide_text: if set to 'n', do not display a '(Hide)' suffix after _text when status is not 'hidden'
 *	- _flip_default_open: if set to 'y', the flip is open by default (if no cookie jar)
 *	- _escape: if set to 'y', will escape the apostrophes in onclick
 *  - _type: button styling. Possible values: default, primary, success, info, warning, danger, link (following bootstrap conventions)
 *     Set different class, title, text and icon depending on whether the button is disabled or selected
 *  - _disabled: set to y to disable the button
 *  - _disabled_class: class to use if _disabled is set to y. Default is 'disabled'
 *  - _disabled_title: button title to use if _disabled is set to y
 *  - _disabled_text: button text to use if _disabled is set to y
 *  - _disabled_icon_name: button icon to use if _disabled is set to y
 *  - _selected: set to y to enable the button. Default is y
 *  - _selected_class: class to use if _selected set to y. Default is 'selected'
 *  - _selected_title: button title to use if _selected is set to y
 *  - _selected_text: button text to use if _selected is set to y
 *  - _selected_icon_name: button icon to use if _selected is set to y
