/*
 * smarty_function_button: Display a Tikiwiki button
 *
 * params will be used as params for as smarty self_link params, except those special params specific to smarty button :
 *  - _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
